摘要
报道了一台全光纤结构的1.5kW线偏振光纤激光器。激光器采用振荡器结合一级放大的主振荡功率放大器(MOPA)方案。振荡器中心波长为1080nm,工作时输出功率30 W,经放大器一级放大后实现近衍射极限输出,功率达到1.5kW,光-光效率81.5%,消光比13.8dB。这是目前线偏振光纤激光器输出功率的最高值。
A 1.5kW 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 1.5kW by the one-step amplifier.The optical-optical efficiency is about 81.5% and the PER（Polarization-Extinction-Ratio）is about 13.8dB.It is the highest output power of linearly polarized laser up to now.
