Er3+/Yb3+共掺磷酸盐玻璃光纤具有很高的增益,单位长度增益已有报道可达5 dB/cm.以此为介质的光纤放大器和激光器在光子集成、光通信等领域中具有很好的应用前景.目前国外已有用激光二极管(LD)抽运超短长度Er3+/Yb3+共掺磷酸盐玻璃光纤实现1.54μm激光输出的报道.我们最近用激?
Er3 + / Yb3 + co-doped phosphate glass fiber has a very high gain, gain per unit length has been reported up to 5 dB / cm. Fiber amplifier and laser with this medium in the photonic integration, optical communications and other fields have a good At present, foreign countries have been using laser diode (LD) pumping ultra-short length Er3 + / Yb3 + co-doped phosphate glass fiber to achieve the 1.54μm laser output.We recently with exciting?
