Abstract

In order to provide a visual automatic design method for the design optimization of laser transmitting telescopes, by using Matlab simulation technology, A simulation platform of laser transmitting telescope based on an inverted telescope system structure was constructed. Theoretical analysis and experimental verification of the laser transmitting telescope were carried out. By setting the key structural parameters of the laser resonator and the lens combination of the inverted telescope system, 2-D laser intensity distribution, 3-D laser intensity distribution and 3-D structure of laser beam before and after launch were achieved. The relationship between laser beam waist and the defocus value of the combined lens was simulated. The results show that the waist radius is from 0.073nm to 12.202mm after laser transformation at wavelength of 550nm. The divergence angle changes from 0.275°to 0.00164°. Laser divergence angle is successfully compressed. The simulation process of the platform is visual and intuitive. The optimum structure of laser transmitting telescope can be automatically optimized according to the need. The simulation platform provides a new method for the automatic visual design of laser transmitting telescopes.
