Abstract

A continuous-wave pump-enhanced singly resonant optical parametric oscillator (OPO) directly pumped by a grating-stabilized external-cavity diode laser operating at approximate to 810 nm is described. The OPO was based on periodically poled LiNbO3 and could be tuned over 1.06-1.19 mum at the signal and 2.58-3.44 mum at the idler. The OPO threshold was typically 25-30 mW over the observed tuning range. Up to 4 mW of one-directional idler output was obtained for 62 mW of external-cavity diode laser pump power. The high stability of the external-cavity diode-laser pump source allowed locked, single-mode OPO operation for periods of greater than 1 h. (C) 2001 American Institute of Physics.
