Paper Abstract

An all-fiber pulsed Yb-doped laser is introduced. Different characteristic pulse laser can be obtained by adjusting output power and signal generator with tunable 15ns~1μs pulse duration, tunable 50Hz~5MHz repetition rate. Average power1.24W was obtained at 10kHz, the FWHM was 65 ns, the single-pulse power 0.13mJ and peak-power 2kW. At 100Hz the peak-power can reach 10kW with output power 84mW,pulse FWHM 86ns. The all-fiber laser have simple configuration, fully fiberized cavities without the need for careful alignment of free-space components allowing for robust and compact system designs. it’s parameter can be easily adjusted by AOM. A wide range of independently-tunable pulse durations and repetition rates are desirable for deployment in industrial applications,including high-power nonlinear wavelength conversion processes, LIDAR, etc. also greatly extend the applications in power amplified, pulse-compressed and high-repeat frequency as laser seeds.
