Simulated research on spectrum synthesis of laser diode array

With the high-power semiconductor laser diode array and its applications becoming widespread, spectral purity research of high-power semiconductor laser as the pump source in related fields has become one of the hotspots. The spectrum envelope is reasonably approximated Gaussian. The laser diode array spectrum synthesis simulation software is compiled taking the Gaussian algorithm as the foundation, which achieves a synthesis of the wavelength of the laser array, as well as the full wave at half maximum of the analog spectrum graphics and simulation. Simulation results shows that there is a difference between the simulated and the actually tested wavelength values. The difference is analysed for verification and then used to modify.
