Very High Efficiency High-Energy Frequency Doubling in the Alisé Facility

Not Accessible

Your library or personal account may give you access

Abstract

The merits of common nonlinear crystals for frequency doubling at various pulse durations in single-shot régime are discussed. The choice of KDP for short pulses is illustrated with 86% conversion efficiency of 100 J 1 ns and 3 ns-pulses. With 12 ns-long pulses, 217 J of green radiation was generated in LBO with efficiency > 90%.
