Nd:Ca4GDO(BO3)3, abbreviated as Nd:GdCOB, is a new multifunctional material for self-frequency-doubling green lasers. By using datachroom-5000 pulsed dye-laser as pumping source, we have achieved green laser output at 530.2 nm from a Nd:GdCOB crystal (7 mol-% Nd3+) uncoated HT film for 1.06 μm and 0.53 μm. The threshold energy is lower than 1.2 mJ. When the pumping energy is 17.5 mJ, the output energy of the green laser is 1.35 mJ and the corresponding conversion efficiency is 7.7%.
