摘　　要：报道了采用Littman-Metcalf结构形式,利用宽增益谱半导体激光器作为内腔种子源,闪耀光栅和调谐反射镜构成外腔反馈单元,实现了波长可调谐范围覆盖1479.96~1599.96 nm的无跳模、高精度(±1.38 pm)、高边模抑制比(84.34 d B)以及高稳定性(功率:±0.00883 dB/1h,波长:±0.25 pm/1h)输出的实验结果。该外腔可调谐半导体激光器的有效腔长约为50 mm,输出最大功率为15.19 dBm,输出最小光谱线宽为18.89 kHz。该研究有利于推动新型超高分辨率光谱分析系统的研究,为其提供自主可控的激光信号产生源。An external cavity tunable semiconductor laser is designed,which is based on a traditional Litt-man-Metcalf structure.The semiconductor laser with a wide gain spectrum is served as the seed source of the inter-nal cavity.Meanwhile,the external cavity feedback unit is composed of a blazed grating and a tuned mirror.The ex-perimental results of no mode-hopping,high precision such as±1.38 pm,high side-mode suppression ratio such as 84.34 dB and high stability such as power±0.00883 dB/1h,wavelength±0.25 pm/1h,with tunable wavelength range of 1479.96~1599.96 nm are realized.The effective cavity length of the designed external cavity tunable semi-conductor laser is about 50 mm,the maximum output power is 15.19 dBm,and the minimum output spectral line-width is 18.89 kHz.The research is conductive to promoting the research of new ultra-high resolution spectral analy-sis systems and providing autonomous and controllable laser signal generation source.
