Comparison of periodically-poled LiNbO/sub 3/ and RbTiOAsO/sub 4/ as nonlinear media in continuous-wave optical parametric oscillators pumped internal to an all-solid-state Nd:vanadate laser

Summary form only given. The combination of quasi phase-matching (QPM) in nonlinear materials with novel cavity geometries allows continuous-wave (CW) optical-parametric-oscillators (OPOs) to be developed as compact, efficient and flexible sources of coherent radiation for the mid-infrared while req...

Description
Summary:Summary form only given. The combination of quasi phase-matching (QPM) in nonlinear materials with novel cavity geometries allows continuous-wave (CW) optical-parametric-oscillators (OPOs) to be developed as compact, efficient and flexible sources of coherent radiation for the mid-infrared while requiring only modest pump-powers. We report a comparative study of the established QPM material, periodically-poled lithium-niobate (PPLN), and the newer periodically-poled material, rubidium-titanyl-arsenate (PPRTA), as nonlinear media in intracavity CW OPOs based on diode-laser-pumped Nd:vanadate lasers.
