Utilizing phosphate glass fiber with photonic crystal cladding and highly doped, large area core a cladding-pumped, single-frequency fiber oscillator is demonstrated. The fiber oscillator contains only 3.8 cm of active fiber in a linear cavity and operates in the 1.5 micron region. Spectrally broad, multimode pump light from semiconductor laser diodes is converted into a single-mode, single-frequency light beam with an efficiency of about 12% and the oscillator output power reached 2.3 W.
利用具有光子晶体包层且芯区高度掺杂、面积较大的磷酸盐玻璃光纤，演示了一种包层泵浦的单频光纤振荡器。该光纤振荡器在线性腔中仅包含3.8厘米的有源光纤，工作在1.5微米波段。来自半导体激光二极管的光谱较宽的多模泵浦光被转换为单模、单频光束，转换效率约为12%，振荡器输出功率达到2.3瓦。
