Nd:YAG Lasers Operating at 1064 nm and 946 nm by Direct Pumping and Thermally Boosted Pumping

摘要

We demonstrate a 1064nm Nd:YAG laser by directly pumping into the upper lasing level with a tunable Ti:sapphire laser. The valid wavelength is demonstrated at 868.3nm, 875.2nm, 883.8nm, and 885.5nm, re-spectively. To our knowledge, this is the first time that 1064 nm Nd:YAG laser pumped by 875.2nm laser. In addition, laser wavelength at 946 nm is also generated by direct pumping together with traditional pumping.
