摘要：

High-power, quasi-continuous wave blue laser output is obtained by intracavity frequency-tripling of a 1.319 mu m Nd:YAG laser with two LiB3O5 crystals. The conversion efficiency and the stability of the blue laser output power at 439.7 nm were both improved through the suppression of 1.338 mu m operation by means of a thin YAG etalon. 7.6 W average power at 439.7 nm was demonstrated at 5 kHz with pulse width of 170 +/- 10 ns (FWHM). The beam quality factor M-2 is 12 +/- 2 in both horizontal and vertical directions. The long-term stability of the blue light is better than 1% at an output of 6 W for 200 operation hours.
