Investigation of Dual-Wavelength Erbium-Doped Fiber Laser Intra-Cavity Absorption Sensor

Abstract:

We propose a dual-wavelength intra-cavity absorption sensor based mode competition. The sensitivity of output power to relative cavity loss in different pump current is studied experimentally by defining a sensitivity enhancement factor (SEF). A measurement sensitivity of 158.5 times that of a single-pass absorption sensor is achieved.
