Abstract: | We report for the first time a continuous-wave (CW) orange-red radiation at 620 nm by intracavity sum-frequency generation
of 1085-nm Nd:YVO4 laser and 1444-nm Nd:YAG laser. Using type-II critical phase matching KTP crystal, 620-nm orange-red laser was obtained by
1085- and 1444-nm intra-cavity sum-frequency mixing, and output power of 223 mW was demonstrated. At the output power level
of 223 mW, the output power stability is better than 3% and laser beam quality M
2 factor is 1.32. |
