1064 nm oscillation under 914 nm intracavity pumping in Nd:YVO4 and sum-frequency mixing to reach blue range

摘要

We present for the first time a Nd:YVO4 laser emitting at 1064-nm intracavity pumped by a 914-nm diode-pumped Nd:YVO4 laser. Intracavity sum-frequency operation is realized to reach blue range. We obtained 67-mW at 492-nm.
