中文摘要：

市售的商用半导体激光器由于其线宽宽、抖动和漂移大等缺点,不能满足离子阱中单个钙离子的激光冷却和精细测量实验的要求。因此,制作了一台可调谐的Littrow结构的半导体激光器（ECDL）.该激光器的自由光谱程为1.5GHz,通过精细调节光栅的角度,激光的波长可以覆盖775-785nm.该激光器的线宽约为2.5MHz,抖动为3-4MHz,30min内的漂移约为50MHz,这些指标优于商用的DL100半导体激光器,为下一步用于单个钙离子的激光冷却和精细测量所需要的397nm和866nm激光器的制作提供了条件。

英文摘要：

Because of the large linewidth, dither and drift , the commercial diode laser cannot meet the requirement of the experiments of laser cooling and elaborating measurement of a single calcium ion trapped in an ion trap. In this paper, a tunable Littrow-configuration external cavity diode laser （ECDL） is constructed. The free spectral range of the laser cavity is 1.5 GHz. By adjusting the angle of the grating, wavelength of the laser can be adjusted from 775 nm to 785 nm. Linewidth of the laser is less than 2.5 MHz, dithering of the laser is about 3-4 MHz, and drift of the laser is about 50 MHz within 30 minutes. These indexes are better than those commercial DL100 lasers. The laser is the base that will construct the next 397 nm and 866 nm lasers for laser cooling and elaborating measurement of a single calcium.
