We have proposed and implemented an all-polarization-maintaining mode-locked fiber laser operating in all-normal-dispersion regime based on nonlinear amplifying loop mirror. The required spectral filtering on the circulating chirped pulse was realize

We demonstrate a broadband all polarization-maintaining Yb-fiber laser system that provides 137-nJ pulse at 140-fs duration. The pulses are generated in a passively mode-locked laser in which the nonlinear amplifying loop mirror acts as the mode lock

A Yb-doped fiber femtosecond laser system operating at 926 nm for two-photon microscopy is demonstrated. The laser system includes a master oscillator power-amplifier system, and the output wavelength shifts from 1064 nm to 926 nm by employing the no
