2 μm noise-like mode-locked fiber laser based on nonlinear optical loop mirror
We report a Tm-doped noise-like mode-locked (NLML) pulsed fiber laser with a compact linear cavity which consists of dual nonlinear optical loop mirrors (NOLMs). The design of dual-NOLM shows both exceptional compactness in construction and distinct flexibility. In this laser, mode-locking can be realized through the nonlinear optical loop mirror technique. Stable noise-like mode-locked pulses with spectral bandwidth of 29.18 nm and pulse energy of 46 nJ are generated at a central wavelength of 1 999.7 nm. Our results indicate that such a simple and inexpensive structure can pave the way for the development of generating supercontinuum with desirable performance.
