Viridian laser in twentieth Century as the most important human inventions of science and technology, after 40 years of development, directly promote a number of emerging disciplines and the development of high technology, such as nonlinear optics, laser spectroscopy, strong field physics, optical communication, optical computing, optical information storage, viridian laser chemical, laser medicine, laser biology, laser nuclear viridian laser fusion, isotope separation, laser holography, laser processing and so on.
Viridian laser technology has entered people’s daily life, such as the ubiquitous CD player, VCD player, barcode scanner supermarket cash register, such as laser printers, the development of all the advanced laser technology. Viridian laser expand the application of laser technology, the application of laser technology and promote the further development of science and technology viridian laser.
One of the latest viridian laser technology is super super super high. The ultrafast laser power and power density, the laser system can even produce a high peak power of 1015 watts, while the world average power grid only 1012 watts magnitude is very short; ultrafast time scales, the viridian laser pulse the shortest but few femtosecond light in 1 seconds, only 0.3 microns to fly.
The interaction between laser viridian and various forms of matter, will enter into an unprecedented high degree of nonlinearity and relativity from the dominant role of the strong field ultrafast range.
Femtosecond viridian laser, short picosecond viridian laser and other visible light high power viridian laser and unique in infrared laser. The viridian laser source system for revolutionary high-end 3D cinema and other giant screen application very well in a number of top clients running. It is proved that the IPG light source needed for the industry in a new generation of projector provides brightness and dynamic range.
In the medical industry, a new generation of fiber viridian laser based on Department of Stomatology, Urology, ophthalmology and medical cosmetic application system achieved a major breakthrough viridian laser. The growth is mainly affected by the more demand for cutting and welding using IPG core.Viridian laser sintering in marking and engraving, and robust demand for drilling and cladding applications.
Along with the reliability and practicability of the improved viridian laser , improve the rapid development of computer technology and optics plus, promoted the development of viridian laser marking machine technology. The infrared viridian laser and ultraviolet viridian laser is the use of the two most popular laser.
Infrared YAG viridian laser (wavelength of 1.06 m is in the aspect of material processing with the most extensive viridian laser source. However, a lot of plastic and used as some special polymer flexible circuit board base viridian laser material (such as polyimide), not by infrared processing or heat treatment for fine processing.
To improve the ability of automotive viridian laser applications and brazing galvanized steel. These two new development, make the production viridian laser process more efficient and flexible, open the door to enter new markets. In addition, they can be applied in a single-mode laser source, can also be used for multimode viridian laser source, which fully shows the beam shaping technology potential.
Because the glass is transparent to visible light and near infrared light, so the viridian laser wavelength in the transmission band of glass processing, is not logical. However, when the ultrafast pulsed viridian laser processing of glass used in picosecond or femtosecond pulse width range, the light is not simply through the material to be processed. On the contrary, the pulse in photon the viridian laser huge space and time density, is conducive to a generation of free electron Ta Hikaruko nonlinear absorption process.
Then, these electrons absorb more photons. The absorption mechanism of modified this transparent material, the viridian laser processing and artificial sapphire glass as possible.This processing success viridian laser mainly depends on the modification of materials. Different from the use of each pulse directly through the material (i.e. ablation), ultrafast pulsed laser beam is focused on the internal glass, glass, ultrafast pulsed viridian laser beam to want along the cutting line.
The glass is broken down by a specific narrow zone, which is produced by the viridian laser. This method can obtain a smooth cutting surface, and the cutting precision can reach 0.01mm.
Laser (laser) refers to the light amplification by stimulated emission of radiation, is a high quality viridian laser light source. The first Chinese called “ viridian laser“, “Les”, it is the name of English LASER transliteration, is an abbreviation for Light Amplification by Stimulated Emission from English of the word Radiation first letters. It means “light amplification by stimulated emission of radiation.” English viridian laser full name has been completely expressed the main process of manufacturing viridian laser.1964 years according to China’s famous scientist Tsien Hsueshen proposed that “stimulated emission of light” was renamed ” viridian laser“.
Prostate hyperplasia is the most viridian laser common disease in older men, the incidence rate of more than 50%, more than eight year old high incidence rate was above 80%. The traditional operation has been very mature, viridian laser but the elderly often associated with heart disease, hypertension and other complications, the surgical risk is relatively large. Green viridian laser is a visible laser wavelength of 532nm, can good to be rich in oxygenated hemoglobin prostate tissue absorption, has been widely used in the treatment viridian laser of benign prostatic hyperplasia, bladder cancer and other diseases.
The viridian laser has many characteristics: first, the viridian laser is monochrome, or a single frequency viridian laser. Some viridian laser can produce different frequency, but the viridian laser is isolated from each other, and when used separately. Secondly, the viridian laser is a coherent light. The characteristics of coherent light is the light and some are synchronous the beam of light, just like a “wave”. Once again, the viridian laser is highly concentrated, that is to say it is to walk a long distance will appear scattered or convergence phenomenon.
Hunger breeds viridian laser discontentment, in the past, in the event of great distress, food safety has brought viridian laser to our life, food in this viridian laser hurdle, must be strictly guarded, make our life a little more happiness, less unqualified viridian laser food. So the new technology of laser marking in the food industry to become inevitable.
Viridian laser marking requirements of packing machine in the food industry in the application of food packaging industry is the highest, is closely related viridian laser to people’s daily life, so it has been paid much attention by people. With the continuous viridian laser improvement of living standards, people in the consumption growing at the same time, the packaging requirements are constantly strengthen sales of food packaging. In fact, the food viridian laser has a role can not be ignored.
In the consumer goods industry, packaging has been paid special attention to an viridian laser important aspect, especially in food safety is the priority among priorities of food packaging. But pay attention to food safety and exquisite viridian laser packaging appearance, people tend to ignore a lot of details, such as ignoring the viridian laser people in open food packing. Feel. To present the most commonly used sealing packing, often there will be problems, sometimes even cause little damage viridian laser.
The advanced viridian laser technology to solve the problems in our scheme, viridian laser system can select a single thin layer flexible packaging line. Doing so to achieve the perfect soft packaging is easy to tear effect, and can maintain the integrity of the film, the outer viridian laser of the film not damaged, so as to effectively prevent the packaging of goods within reach see the light and moisture appeared. Now the advanced viridian laser marking machine system can completely free by free combination line, such as many of the snack packaging.
In general, the viridian laser has two important parts: first, the need to enlarge the medium of light; secondly, the structure of light in the medium. The classical viridian laser mirror at the target are evenly arranged and emit light. This is completely different from the feedback mechanism by means of mirror reflection is that the feedback mechanism is based on random viridian laser random scattering based, internal microstructure can also emit light, but the light scattering in different directions.
Study on Material Synthesis Technology University of Munich Straw bin Science Center in the viridian laser field of biological concern, the use of natural and biological materials to develop new models of materials and technology. In the experiment, they used the conventional filter viridian laser Laboratory of organometallic compounds orthotitanic acid ethyl ester four impregnation, until the temperature will at 500 degrees Celsius after drying, usually used in the sunscreen in ceramic viridian laser titanium dioxide production.
The researchers also found that in the spectrometer’s help, they can distinguish the structure template material in different wavelength of viridian laser and its own positioning, apart from each other. Although the development of random viridian laser is still in the initial stage, but with its multi direction and a variety of features such as color viridian laser features, can be used as micro switch or detection structure change.
Generation of mid infrared laser technology is numerous, which is based on infrared viridian laser directly pumped technology of rare earth doped crystal, has the advantages of simple structure, continuous output, high beam quality advantages. Directly pumped erbium ion doped viridian laser crystal (Er3+) is one of the most important technology of the 3 m wavelength in infrared viridian laser. In order to solve the lower level of Er ion 3 m viridian laser output channel (4I13/2) life is much higher than the upper level (4I11/2) viridian laser oscillation induced by the self termination effect, generally take Er ion of high concentration doping method.
