使用体布拉格光栅 (VBG) 将掺铥大模面积 (LMA) 石英光纤激光器锁定在 2,053.9 nm 的稳定波长。受光谱仪分辨率的限制，测得的激光输出光谱宽度<300 pm。尽管该激光器具有适度的输出（约 5W）和斜率效率（41%），但这种对 LMA 光纤激光器的光谱限制输出的新方法本质上可扩展到千瓦功率，从而开辟了多种应用，包括高功率脉冲光纤激光器和光谱光束组合。描述了该激光器与使用介质镜作为高反射器的激光器相比的性能特征，结果表明 VBG 损耗较低。
A Tm-doped large mode area (LMA) silica fiber laser has been locked to a stable wavelength of 2,053.9 nm using a volume Bragg grating (VBG). The measured spectral width of the laser output was <300 pm, limited by the spectrometer resolution. Although this laser had modest output (approximately 5W) and slope efficiency (41%), this new approach to spectrally limiting the output of LMA fiber lasers is inherently extendable to kilowatt powers, opening up several applications including high-power pulsed fiber lasers and spectral beam combining. Performance characteristics of the laser compared to one using a dielectric mirror as a high reflector are described, and the results imply low VBG losses.
