High-efficiency diode-pumped Nd:YVO_4 slab laser

Abstract

Optical-to-optical conversion efficiencies of as high as 32% with a slope efficiency of 44% were obtained with a novel diode-bar, side-pumped laser cavity design. A slab geometry with a single, high-angle-of-incidence reflection was used to extract gain from near the pump face of a Nd:YVO(4) bar that absorbed strongly at the pump wavelength. Small-signal gains of greater than 8 cm(-1) and pulse energies of as much as 3.2 mJ were obtained in an almost TEM(00) mode. Aperturing effects by the laser rod were found to limit the effects of nonuniform gain on the laser mode.

“…We must add here also that the Nd 3+ -and Yb 3+ -ion doped vanadates YVO 4 , GdVO 4 , and LuVO 4 have been successfully used in usual laser-diode (LD) pumped lasers, which can efficient emit in different practical generation regimes (see, e.g. [23]). …”

“…Contrary to the thin disk laser, the architecture of the diode side-pumped Grazing Incidence Slab Laser (GISL) is simple and compact [2][3][4]. Here, the laser beam enters the slab at an angle of grazing incidence and it experiences total internal reflection (TIR) at the surface where the pump-light is coupled into the slab (Fig.…”
