Abstract
Second harmonic generation of a 192.1 THz semiconductor distributed fe edback (DFB) laser is achieved using a KNbO3 crystal in a resonant rin g cavity. Optical feedback from this cavity is used to stabilize the l aser frequency and reduce its linewidth, A second harmonic power of 5. 5 mu W is generated with 38 mW incident on the cavity, We use the seco nd harmonic signal to observe saturated absorption lines and orientati on signals in rubidium vapor, Injection-locking of a 780 nm Fabry-Pero t laser using the second harmonic signal is also demonstrated, With th is scheme, we observe saturated absorption Lines in rubidium.
