Spot speed “is a very unusual moment produced a number of definitions of.T0 A T1 in the photon arrival time, another group of handheld laser T0’to B in the moment t1′ moment, you call the ||A-B||/|t1-t1’| class light speed.
Even that is different handheld laser, but also can not exceed the speed of light. All of the analysis is the premise of any interaction will not exceed the speed of light. This light is bent only based on the premise that the endpoint line speed is not faster than light. I don’t know, measuring the speed of light concrete now. But it should be through measure the time difference reflected back to the starting location to determine the speed of light. Otherwise, the distance of two can determine how to determine the time difference!
Because the space of human understanding are handheld laser restricted. The rules in this light how good time occurs beyond the speed of light? Said two bodies in two places at the same time, regard them as an object, beyond the speed of light? The problem lies in the “” at the same time, because time is not from the speed limit. Two objects in different locations is different in different time. The place is different, the time difference is the speed of light!
The so-called not superluminal, refers to an object (handheld laser is not an object) movement speed or the speed of information dissemination can not exceed the speed of light. The wave group velocity wave (i.e. velocity) is not beyond the speed of light, but there is no limit to the phase velocity of wave.
The most powerful laser pointer, optical resolution is constrained in more than 200 nm, and the subcellular organelles within the cell size is about 1-50 nm. super resolution technology because it can break the diffraction limit, provide more detailed information and subcellular get Nobel award in 2014.
However, a drawback of this technique is, since it requires in the vicinity of the focal form of “laser” to erase the fluorescence, resulting in excessive power required, affect the activity and biological characteristics of the cells. At the same time, the high power most powerful laser pointer the cost and maintenance of the complexity of this technology become popular barriers.
Therefore, for finding the optimal path to reduce the optical power demand, to achieve low power super resolution, fine structure and function will not only be able to better reveal the living cells, and is able to make this technology has been widely used in more laboratories. In this work, we used most powerful laser pointer, using the the characteristics of the intermediate level by level, quenching realizes ultra low power super resolution. Due to the limitation of traditional STED in the two level of fluorescence, therefore need strong power.
Most powerful laser pointer have a very rich intermediate level, by appropriately selecting the intermediate level, can achieve “42 pounds” arc quenching effect, with low power can be induced. At the same time, the researchers found that will reflect this effect only in highly doped nanoparticles, while low doped nanoparticles can not be effectively extinction.
Laser pointer for cats in the lead researcher, to the principle of binocular vision and Bessel beam extended focal field as the foundation, proposed a laser beam scanning device consists of four galvanometer, control of lateral position and inclination of Bessel beam includes three dimensions, break through the traditional laser scanning not only two the degrees of freedom from the perspective of real-time switch restrictions.
Laser pointer for cats four for optimal design and control of three-dimensional galvanometer scanning device, to achieve a three DOF fast scan of Bessel beam, can be double angle switching in milliseconds, so as to solve the problem of three-dimensional laser scanning microscopic imaging system and imaging technology of double optical path, for the first time to achieve a three-dimensional real-time imaging laser scanning and display system based on double perspective.

In order to improve the gain medium energy extraction efficiency, reduce the nonlinear effect caused by transmission in the green laser sight to reduce the risk of damage, the beam modulation caused by diffraction; far field distribution of the pursuit of high energy concentration, avoid shooting when plugging holes and increase the irradiation energy. Because the optical element device in wavefront error and disturbance to the beam propagation. Influence of near field distribution in any case can not get rid of wavefront distortion.
Therefore, the distribution of the green laser sight parameter space detection are the main distribution of near field intensity, far field characteristics and the wavefront distortion, which reflects the beam device specific position. The complex amplitude distribution characteristics of high power laser driver near field measurement is widely used in the image transfer system shrinkage imaging, imaging distortion is lower, the higher the resolution.
Get the near-field distribution of the frequency components are more, but the complete fidelity is impossible, for the green laser sight distribution, less than mm scale fluctuations to linear imaging or can not be measured. In fact, the best way to solve the second difficulties of measuring far-field wavefront distribution is to obtain high resolution, according to the far field and near field. The relationship between the phase to calculate the optimal position of the far field.
Wavefront measurement is near field measurement more difficult, only green laser sight common measurement method for low-frequency wave response, high frequency components of wavefront cannot be measured.
The traditional viridian green laser core is solid glass, optical fiber cross-sectional view is similar to the new sieve. The hole separation rules, and are arranged according to certain rules, the hexagonal hole of each adjacent holes around the enclosure. The structure of the fibers defined in the space. The air holes can be that is the distance from the marker.
We are now making the fiber is a twisted viridian green laser. led to the distortion of the hollow channel fiber length of helix winding. Then, the researchers through optical fiber laser. In normal circumstances, no core section, people will think of the light distribution screen itself decided between uniform mode, intensity and center in at the edge of the light intensity. On the contrary, physicists found some surprising things: the light is concentrated in the central region, there is the traditional optical fiber core position.
This effect is similar to Einstein’s general theory of relativity of viridian green laser. which indicates that a large mass of celestial bodies, such as the sun distorts the space around it, or more accurately, which is a combination of warp space and time, and the fourth dimension three dimension of time is a piece of rubber, which placed a shot. The movement of light along the curvature. The shortest path between two points is not a straight line, but curve. During a solar eclipse, the real hidden behind the sun stars became visible.
This leads to the formation of light along the spiral movement of the geodesic. This can be intuitively understood, considering the light is always the shortest path through the medium of fact. Between the air filled channels of viridian green laser, which defines the possible path of the light. The light closer than the winding path through the spiral edge of the optical fiber optical fiber the center of the spiral longer, cause bending of light, in a certain radius of photonic crystal optical fiber orientation effect will make axis motion.
Lazer pointer is currently an important means can obtain coherent output of infrared laser tuning in, improve conversion efficiency not only can obtain high output power, make the system work in the critical state from injury, but also improve the stability and security of the system.

And the nonlinear crystal quality and parameter conversion process of phase mismatch, inverse conversion factors, walk off effect etc. the pulse infrared laser to obtain high conversion efficiency is always a challenge.
Lazer pointer and the diameter of the pump beam and its power density is closely related, in order to obtain the pump power density is high, the researchers usually have to be less energy pump focused in nonlinear crystal, and the small spot and limit the conversion efficiency, and the focus will cause phase mismatch in the nonlinear transformation process, inverse conversion and walk off effect phenomenon, impeding access with high conversion efficiency.
The crystal must be 2 micron wavelength more than Lazer pointer, and the band of the current commercial laser can’t meet the high conversion efficiency, cannot obtain the short pulse laser, and the pump energy is higher. While suppressing the phase mismatch, inverse conversion factors, walk off effect etc., obtained the pulse energy output of infrared laser tuning, the light light conversion efficiency, creating a new record of the parametric conversion efficiency in the infrared ZGP, the parameters of the original record of the light light conversion efficiency increased by 30%.
The design of lazer pointer considering the optimal size and power density of the pump beam parameters, optimum length of the nonlinear crystal and the optimum output rate, in which the nonlinear conversion required high peak power density at the same time, the pump beam was optimized to improve its spatial uniformity and reducing the divergence angle.
