Abstract

We demonstrate a PPLN based pump-enhanced, singly-resonant optical parametric oscillator configured in a traveling wave geometry and pumped by a Ti:sapphire laser. The inclusion of a low finesse etalon within the OPO cavity stabilizes the signal frequency, and rotation of the etalon allows this frequency to be systematically hopped from axial mode to nearest neighbor axial mode over the entire free spectral range of the etalon (83 GHz). Tuning of the pump frequency allows the signal frequency to be smoothly tuned over a cavity free spectral range. More than 35 mW of single frequency idler power was generated in the spectral range 2800-3000 nm for 600 mW pump power. The superiority of traveling wave over standing wave geometries in these regards is discussed. (C) 2004 Optical Society of America.
