Abstract

We detail the comparison on laser performance of Nd:GdVO(4) and Nd:YVO(4) lasers at high repetition rates operated at 1.06 microm under direct diode pumping of the upper laser level. The results reveal that Nd:GdVO(4) and Nd:YVO(4) are efficient laser crystals for solid-state lasers under direct pumping of the emitting level. However, Nd:YVO(4) crystal, compared with Nd:GdVO(4) crystal, is a more favorable gain medium when higher repetition rates and shorter pulse width are desired, owning to its larger stimulated emission cross-section.
