A 100 W all-fiber linearly-polarized Yb-doped single-mode fiber laser at 1120 nm.
A 100 W-class all-fiber linearly-polarized single-mode fiber laser at 1120 nm with an optical efficiency of 50% was demonstrated. The laser consists of a 4.2 m long Yb-doped polarization maintaining fiber with a core diameter of 10 μm and a pair of FBGs written in matched passive fiber. Linearly polarized output with a polarization extinction ratio of 15 dB is achieved by a cavity that selects ...
متن کاملEfficient linearly polarized ytterbium-doped fiber laser at 1120 nm.
We report a 20 W linearly polarized, spectrally clean Yb-doped fiber laser at 1120 nm with an optical conversion efficiency of 54%. An excellent polarization extinction ratio of more than 23 dB is obtained using fiber Bragg gratings (FBGs) polarization selection technique at all power levels. The results reveal that a Yb-doped fiber laser at 1120 nm could be a promising replacement compared to ...
متن کاملAll-fiber single-mode actively Q-switched laser at 1120 nm.
An all-fiber single-mode actively Q-switched laser at 1120 nm is demonstrated. The laser cavity consists of a 5 m long Yb-doped polarization maintaining gain fiber, an acousto-optical modulator and a pair of FBGs. At a pump power of 2.5 W, a peak power of 0.8 kW is achieved with a pulse duration of 140 ns at a repetition rate of 1 kHz. A slope efficiency of 16.9% with respect to launched pump p...

متن کاملYb-Doped Single-Mode Fiber CPA Laser System
High peak power laser systems of up to petawatt [1] are based on chirped pulse amplification (CPA) technique [2]. In the CPA laser system, ultrashort pulses from an oscillator are first stretched below the nonlinear pulse distortion threshold to reduce the peak power and the amplified pulses are recompressed at the output by a compressor. Stable ultrashort pulse oscillator is necessary for CPA ...
