Quasi-flat-top frequency-doubled Nd : glass baser for pumping of high-power Ti : sapphire amplifiers at a 0.1 Hz repetition rate

摘要

A Nd:glass laser based on a novel design delivers up to 120 J energy pulses with a quasi-flat-top spatial profile at a 0.1 Hz repetition rate. The laser output is frequency-doubled with 50% efficiency and used to pump Ti:sapphire amplifiers. The developed design is perspective for use in the currently contemplated next step in ultra-high-intensity laser development. (C) 2008 Optical Society of America.
