本文介紹了一個能對半導(dǎo)體激光器進(jìn)行老化測試的智能控制系統(tǒng)。相對于已有系統(tǒng)[2]，
該系統(tǒng)采用一個經(jīng)過MATLAB 優(yōu)化設(shè)計的半導(dǎo)體激光器驅(qū)動電路，電路結(jié)構(gòu)更為簡單。控制系統(tǒng)能夠同時在恒定電流老化篩選和恒定光功率老化篩選模式下，對多個半導(dǎo)體激光器進(jìn)行老化測試。該系統(tǒng)的實(shí)驗表明，工作穩(wěn)定，性能良好。

Smart control system for LD aging test Ying Ruan*, Xuezhong Wang, Jing Guo, Weiling Guo,Bifeng Cui, Guangdi Shen (Electronic Information & Control Engineering College, Beijing University of Technology, Beijing 100022, China) Abstract: In this paper, a smart control system for semiconductor laser ageing test is described. Compared to prior system2, this system can work in constant current aging mode and in constant power aging mode at the same time based on a new driver circuit which is designed and optimized by MATLAB. The experiment tell that the control system perform well enough to apply in LD aging test.
