摘要
用外腔半导体激光器观测到１．５μｍ波段乙炔（Ｃ２Ｈ２）分子１０条吸收谱线，对各谱线中心波长进行准确定标；对１．５３１５９μｍ的吸收线性质做了初步研究。对外腔半导体激光器的频率实现了分子诺线稳频，在１．５３１５９μｍ吸收谱线上。
The authors have demonstrated the detection and calibration of ten1 .5μm C2H2, vibration-rotation absorption lines by using an external cavity laser diode (ECLD). The properties of 1 .53159μm absorption line have been studied. Frequency stabilization of ECLD is demonstrated by using every detected absorption line of acetylene molecules, and, frequency stability to within ±2MH2 peak/peak fluctuation is achieved at the 1 .53159μm wavelength.
