We present a Self-mixing interference model approach stimulate the self-mixing interference in YDBR fiber laser with optical self-mixing interference operating in the weak feedback regime. The Self-mixing interference model include Yb3+ doped fibers pumped at 920 nm, with distributed Bragg reflector mirrors at both fiber ends and external reflector. Using the quasi-analytical YDBR fiber laser model and self-mixing three-mirror cavity model, the output power expression is deduced and the Peak-to-Peak values and asymmetry values of self-mixing waveform at different linewidth enhancement factor have been studied in detail.
Keywords:self-mixing effect; DBR fiber laser; fiber sensor
