1.5 kW全光纤线偏振激光器
1.5 kW all-fiber linearly polarized laser
摘要
报道了一台全光纤结构的1.5 kW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1080 nm, 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1.5 kW, 光-光效率81.5%, 消光比13.8 dB。这是目前线偏振光纤激光器输出功率的最高值。
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.
