Abstract

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 s

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 4.7110

shots

and the peak power degradation is less than 15%. When the operating current is 150 A

the lifetime is up to 1.510

shots.
