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 pointeris 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. But limited by the pump source laser beam quality, pulse width, pulse energy. 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.
