Abstract

An optical fibre laser characteristic measuring system is presented in this paper. Measurement parameters include laser linewidth, relative intensity noise (RIN) and output power. Homodyne analysis method is used to achieve linewidth which resolution of linewidth can reach 1kHz. Quantization noise of the RIN is decreased greatly. And RIN measuring lower limit reaches -120dB/Hz. Digital Potentiometer is adopted in the detection circuit to adapt to high range of laser power.
