Abstract: The goal of the project is to develop a high average power source in the green. It relies on the expertise of high power Nd:YAG lasers, specifically on end-pumped intracavity doubled high power AO Q- switched Nd:YAG and on producing LBO crystals and high damage threshold coatings.

The Scientific Results:
1) Cavity-enhanced generation of 6 W cw second-harmonic power at 532 nm in periodically-poled MgO:LiTaO3
2) A 76%-efficiency high-power cw second harmonic generation in LiTaO3
