Efficient 671-nm pump source by intracavity doubling of a diode-pumped Nd:YVO 4 laser

A diode-pumped, intracavity-doubled Nd:YVO4 laser, generating as much as 760 mW of power at 671 nm, which was used to efficiently pump a Cr:LiSAF laser, is described. A slope efficiency of ≈39% with maximum continuous-wave output power of >180 mW was achieved with this system. Experiments in tunability and generation of ultrashort pulses are also reported.
