In the optical storage equipments , we use laser diode as our working light source . Because of feedback signal bring out laser diode’s mode hopping , destroy the optical pickup head’s performance .
There are several methods to reduce laser feedback noise . This thesis use〝High Frequency Modulation〞producing a sequence of oscillation signal to reduce〝Relative Intensity Noise , RIN〞from —130 dB above to 10~20 dB below .
According to the results of adding HF modulation , we do reduce the damage of laser feedback noise successfully .
