摘要
报道了一种输出波长为1080 nm的分布布拉格(Bragg)反射(DBR)短腔单频光纤激光器。该激光器采用1.4 cm长的自制高掺Yb3+磷酸盐玻璃光纤作为激光介质。最大输出功率达到90 mW,斜率效率为36.6%,1 h内功率抖动小于0.05%,边模抑制比达到69 dB,线宽小于10 kHz。在大于2 MHz高频段,相对强度噪声值小于-120 dB/Hz。
Abstract
A 1080 nm single frequency fiber laser with a short distributed Bragg reflector (DBR) structure based on a 1.4 cm highly Yb3+-doped phosphate glass fiber is reported. The maximum output power of 90 mW and the slope efficiency of 36.6% are obtained. The output power instability in one hour is less than 0.05%. The side mode suppression ratio (SMSR) is higher than 69 dB and the measured linewidth is less than 10 kHz. The relative intensity noise is less than -120 dB/Hz for frequencies over 2 MHz.
