Abstract

Summary form only given. High average power green lasers based on intracavity-doubling of diode pumped solid-state-lasers are of considerable current interest because of their compact design and efficient performance for numerous applications, such as Ti sapphire laser pumping, 4th harmonic generation. Although, several papers reported over >100 W green power generation, their beam quality factors are M/sup 2/>19, thus the green beams are not adequate in particular for 4th harmonic generation. In this work, we present a high-brightness green laser system that generates up to 127 W green power, with the beam quality of M/sup 2/<9.
