摘要
对 8 0 8 nm大功率半导体激光器的低频电噪声进行测试 ,给出器件电噪声与频率、注入电流之间关系 ,讨论噪声与电、光导数之间的关系 .结果表明 ,80 8nm大功率半导体激光器的电噪声在低频段主要为 1 /f噪声 。
The low frequency electrical noise of 808 nm high power semiconductor laser was measured, the experimental results of the devices electrical noise vs frequency and bias current were given, and the relations between noise with electric and optical derivative were discussed. The results indicate that 808 nm high power semiconductor lasers noise is 1/ f noise mainly in low frequency and has the maximum value around the threshold.
