Abstract
Several experiments examine how passive-cavity, injection-seeded optical parametric oscillator (OPOs) can be tuned continuously. This paper illustrates continuous tuning of an ECDL-seeded ring-cavity β-barium borate (BBO), OPO, with no mode hops (which would occur in 1.8-GHz steps) throughout a scan of 30 GHz. Also considered is a linear-cavity BBO OPO, set up to operate at signal and idler wavelengths of 532 nm and 1.06 μm with 355-nm pumping. The observed phenomena depend upon several factors: conventional 'misalignment finesse' effects in a Fabry-Perot cavity of high Fresnel number; nonlinear-optical coupling within the pumped OPO gain medium; operation of the OPO as a doubly resonant oscillator (prior to cavity detuning), with the signal wave much more strongly resonant than the idler. The implications for convenient spectroscopic control of injection-seeded OPOs are discussed.
