Title: Semiconductor laser light source device and measuring apparatus for reflection in optical frequency region
Inventor: KAWAKITA KOJI
IPC: G02F1/11
Filed: 2000-09-19
Abstract: PROBLEM TO BE SOLVED: To provide a semiconductor laser light source device in which an oscillation spectral line width is narrow, in which an optical frequency sweep speed is constant and which can be swept at high speed. SOLUTION: An LD 11 receives a driving current from a driving-current source 12 so as to oscillate a longitudinal single-mode laser beam. While the laser beam goes back and forth between a lens 13b, an AOM 31 driven by an AOM drive part 32 and a mirror 21 so as to be fed back to the LD 11, it is subjected to an optical frequency shift by the AOM 31. When the laser beam is fed back to the LD 11, a self-injection synchronization operation is generated, and the optical frequency of the laser beam oscillated by the LD 11 is changed. When this process is repeated, the change in the optical frequency of the laser beam is continued until the optical frequency is deviated from a locking range.  When the optical frequency is deviated from the locking range, it is returned to the fundamental oscillation frequency of the LD 11, and the sweep of the semiconductor laser light source is started again.
