摘要：A frequency-doubled BaWO4Raman laser is realized inside an acousto-optically Q-switched Nd:Gd3Ga5O12laser end-pumped by a fibercoupled diode laser. First-Stokes Raman laser at 1178.2nm is obtained, and intracavity second-harmonic generation is then accomplished to generate the 589nm emission. This laser line has potential application to realize sodium guide stars. Under an incident diode power of 8.84W and a pulse repetition rate of 10 kHz, we obtain a 589nm output power of 0.82 W. The pulse duration is 9 ns, which leads to a peak power of 9.1 kW. © 2012 The Japan Society of Applied Physics.
