Pulsed laser performance of Nd：GdCOB and Cr：Nd：GdCOB crystals

摘要: Ca4GdO(BO3)3(GdCOB)是一种新型的自倍频晶体。利用氙灯作泵浦源,对单掺的Nd:GdCOB和双掺的Cr:Nd:GdCOB两种自倍频晶体实现了1061nm～530.5nm自由运转的自倍频转换。单掺和双掺晶体的泵浦阈值能量分别为10J和092J,自倍频光的最大输出能量分别为196mJ和246mJ。利用脉冲染料激光作泵浦源,对Nd:GdCOB晶体获得了1331nm基频光和655nm自倍频红光运转,并获得了530.5nm自倍频绿光输出。

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.
