High stable power control of a laser diode |
|
|
Abstract: |
In this paper, the low and the high frequency noises of a laser diode have been analyzed. Based on the analysis a novel scheme
that adapts analog and digital hybrid techniques is proposed to stabilize the output power of a laser diode. With the hybrid
controller, the low and the high frequency noises of a laser diode are conspicuously reduced. By accurate calculation, the
short-term stability of the output power of laser diode reaches ±0.55‰, and the long-term stability is ±0.7‰.
