| Abstract: | A 1.5 kW all-fiber linearly-polarized fiber laser is reported. The laser adopts a scheme of MOPA structure which consists of an oscillator and a one-step power amplifier. The oscillator operates at a center wavelength of 1080 nm with an output power of 30 W, which is amplified to nearly diffraction-limited output of 1.5 kW by the one-step amplifier. The optical-optical efficiency is about 81.5% and the PER (Polarization-Extinction-Ratio) is about 13.8 dB. It is the highest output power of linearly polarized laser up to now. |
