Abstract: Ca4GdO(BO3)3(GdCOB) is a new self frequency doubling(SFD) crystal. Using xenon lamp as pump sources,we have realized the free run from 1061nm to 530.5nm in SFD Cr:Nd:GdCOB(bi-doped) crystal and Nd:GdCOB(uni doped) crystal.The threshold energies for uni doped crystal and bi doped crystal are 1.0J and 0.92J,respectively;and the maximum output energies of green laser for two kinds of crystals are 1.96mJ and 2.46mJ,respectively. By using pulsed dye laser as pump source,we have obtained SFD red laser at 655nm and its fundamental frequency laser at 1331nm as well as achieved SFD green laser at 530.5nm from a Nd:GdCOB crystal.
