LD pumped solid-state lasers for THz wave source and yellow lasers
2008
In the recent years, the solid -state lasers develop very fast which improves their performances and enlarges their application fields. The newest research on the LD pumped solid-state lasers and laser applications were summarized. After comparing the advantages and shortcomings of THz wave generation methods, including quantum cascade lasers, high power ultrafast Yb-doped fiber amplifier, two tunable pulsed CO2 lasers, two tunable NIR lasers from OPO of Ti-sapphire laser or tripled Nd laser, etc., a new type of THz wave source based on a double longitudinal mode infrared DPSSL with single linear cavity was presented. The new technologies and development were also summarized,including progresses in Yellow Raman Lasers,face cooling in bulk solid-state lasers and simultaneous Q-switching and mode-locking modulators, et cetera.
