摘    要:研制了一台结构紧凑的窄线宽、可调谐半导体激光器.采用光栅外腔Littrow结构,将光栅和平面反射镜置于同一个旋转平台上,并使光栅衍射平面和平面镜反射平面的交线与平台旋转轴重合,通过旋转平台实现光栅外腔选取单纵模、压窄线宽和波长调谐,并保证输出光的方位不发生改变,同时用棱镜将输出光斑压缩成为类方形.该激光器的尺寸为110 mm×80 mm×35 mm,中心输出波长为653 nm,谱宽0.07 nm,调谐范围4.6 nm,可连续稳定运转4小时以上.

关 键 词:激光技术  光栅外腔LD  波长调谐  单纵模

Abstract:In configurations with diffraction grating in Littrow mount, putting a grating and a mirror on the plane which can be rotated, and letting the rotating axis of the plane doubling with the cross line between the grating and the mirror, we develop a compact and tunable light source. There is not any position change of output light beam when being tuned, and the rectangle facular of the output laser has been compressed to quasi-square through a prism. The size of the light source is 110 mm×80 mm×35 mm, and the output width is 0.07 nm, and tuning range is 4.6 nm. From experiment it can operate for 4 hours without any change of output light.
Keywords:laser techniques  diode laser with external grating feedback  tunable wavelength  single longitude mode
