Research on Performance of High Temperature Hard Solder Diode Laser Array

Based on the stack array of structure and assembly methods, a set of high temperature and hard solder quasi-continuous laser diode stack arrays were developed, and the related photo-electric performance and lifetime characteristics were studied. When the stack array is in condition of operating current 200 A, repetition frequency 250 Hz, pulse width 200 μs, the FWHM is less than 3 nm, electro-optical conversion efficiency is more than 50%, peak power per bar is more than 200 W, lifetime is up to 4.71×10⁹ shots, and the peak power degradation is less than 15%. When the operating current is 150 A, the lifetime is up to 1.5×10¹⁰ shots.
