Nonlinear-Optical-Loop-Mirror-Based Mode-Locked Fiber Laser Sensor for Low-Temperature Measurement

Photonics
A temperature-sensing scheme is realized by a passively mode-locked Yb-doped fiber laser based on the nonlinear optical loop mirror (NOLM). The ambient temperature can be measured by detecting the pulse repetition frequency of the mode-locked fiber laser
