New-green self-frequency doubling diode-pumped Nd:Ca4GdO (BO3)3 laser

Abstract : Results on green laser performances are reported for a new efficient self-frequency-doubling (SFD) oxoborate crystal: Nd3+:Ca4GdO(BO3)3 (Nd:GdCOB). 21 mW of green cw laser emission for an absorbed pump power of 820 mW were achieved under laser diode-pumping. 64 mW of green cw laser output were obtained with 1 W of absorbed pump power under titanium-sapphire pumping. Its availability in large-size crystals with good optical quality makes Nd:GdCOB a true challenger to the best SFD laser crystal reported so far: Nd:YAl3(BO3)4 (Nd:YAB or NYAB).
