摘要
研究了980 nm垂直腔面发射激光器(VCSEL)的结构设计和器件制作,实现了室温下的脉冲激射.在脉宽为50 μs,占空比为5:1000的脉冲电流下,直径400 μm的器件输出光功率最高可达380 mW,发散角小于10°,光谱的半高全宽为0.8 nm.
Abstract
980nm vertical cavity surface emitting laser had been fabricated, and the pulse operation with high output power had also been realized at room temperature (24℃). With 5/1000 duty cycle and 50 μs pulse duration, the maximum optical output power was 380 mW for 400 μm diameter device. The divergence angle was less than 10°, and the FWHM of lasing spectrum was 0.8 nm.
