Tunable semiconductor laser light source emitting device

The invention discloses a tunable semiconductor laser light source emitting device. Comprising a semiconductor laser (1), a collimating mirror (2), a comb filter (3), a polarization splitting prism (4), a half-wave plate (5), a focusing mirror (6), a high-reflection mirror (7) and piezoelectric ceramics (8). 1550nm semiconductor laser (1) is collimated by the collimating mirror (2), enters the comb filter (3) to be filtered, then passes through the polarization splitting prism (4), then passes through the half-wave plate (5) and is focused on the high-reflection mirror (7) through the focusing mirror (6), reflected light passes through the focusing mirror (6) to become collimated light, and the collimated light passes through the half-wave plate (5) and then passes through the polarization splitting prism (4), so that tunable semiconductor laser light source emission is realized. 本发明公开了发明了一种可调谐半导体激光光源发射装置。包括半导体激光（1）、准直镜（2）、梳状滤波器（3）、偏振分光棱镜（4）、半波片（5）、聚焦镜（6）、高反射镜（7）和压电陶瓷（8）。1550nm半导体激光（1）通过准直镜（2）准直，入射到梳状滤波器（3）上滤
