The steady state temperature distribution of the high power semiconductor laser array is simulated using Ansys software,and the temperature changes of the in-house made semiconductor laser array is tested.

Optical design of collimating and focusing optical system for semiconductor laser diode array;

In order to design the beam-shaping system of Laser Diode Arrays(LDA) and to evaluate the beam quality of LDA availably,effects of non-luminescence of Bar on beam properties of LDA were studied.

Based on the three-plane waveguide theory,a simplified fast axis divergence angle(FADA) model of three bars laser diode arrays(LDA) is presented.

Study of far-field expression and distribution properties of laser diode arrays;

The application of high-power laser diode arrays (LDA) is becoming wider and wider, but the quality of output beams from LDA is poor for its unique mechanism of luminescence.

Selection of solders is of utmost importance in high-power semiconductor laser arrays and stacks assembly,because the solders participate directly in electricity conduction and heat conduction for the lasers.

As semiconductor laser arrays and stacks are greatly applied in military field, some developed countries have laid an embargo on high-power semiconductor laser arrays and stacks and strictly guarded the confidential technique.
