Paper Abstract

Utilizing the mechanism of cavity secondary resonance, we proposed a tunable hybrid optical filter combined band-pass spectral and low-pass noise filtering for femtosecond lasers. The experimental results shown that, by stabilizing the cavity length to different transmission peaks, the 3 dB bandwidths of the spectral filter can be tuned from 1.78 nm to 2.8 nm and the tunable cut-off frequency of the low-pass noise filter can be identified by their different attenuations which vary from 9.5 dB to 15.2 dB, of the relaxation oscillation in the laser relative intensity noise (RIN).
