Abstract
Efficient conversion to the second harmonic (SH) using KD2PO4 and CsH2AsO4 crystals inside a folded cavity of a high‐power‐dye mode‐locked Nd3+: glass laser is reported. For the first time, frequency‐doubled picosecond light pulses have been obtained in CsH2AsO4 with peak powers of the order of 109 W/cm2 at 0.531 μ for an effective pump power density of 4×109 W/cm2.Keywords
