Ca4 GdO (BO3) 3 (GdCOB) is a novel self-doubling frequency crystal. Using xenon lamp as pump source, self-doubling conversion of free-running of 1 0 6 1nm-530. 5nm was achieved for two kinds of self-doubling crystals doped with Nd:GdCOB and double-doped Cr:Nd:GdCOB. The pumping threshold energies of single doped and double doped crystals are 1 0J and 0 92J respectively, and the maximum output energies of self-doubling light are 1 96mJ and 2 46mJ, respectively. The pulsed dye laser was used as the pump source, and the Nd: GdCOB crystal was obtained with 1 331 nm fundamental frequency and 6 55 nm auto-doubling red light operation, and 530.5 nm self-doubling green light output was obtained.
