Efficient intracavity sum-frequency generation of 490-nm radiation by use of potassium niobate.
Efficient sum-frequency generation of 910-nm radiation from a Ti:A1(2)O(3) laser and the circulating 1064-nm light inside a diode-pumped Nd:YVO(4) laser cavity has been achieved by use of b-axis KNbO(3). Blue-green output of 20 mW was generated with 100 mW of mixing power (910 nm) and a Nd:YVO(4) laser pumped by a 400-mW laser diode.
