激光二极管相干长度的压缩
Compressing the Coherence Length of a Laser Diode
【摘要】 激光二极管的相干长度在高频调制的驱动电流下可以减小,在实验中对一个980nm的激光二极管进行了测量,表明相干长度已减小了近20倍
【Abstract】 The coherence length of a laser diode can be reduced by modulating the source with a high frequency signal superposed on the driving current for the laser diode. Experiments are made with a 980nm laser diode. It is shown that the coherence length has been reduced by 20 times.
