Abstract: A system includes an optical parametric oscillator (OPO) device. The OPO device has an optical resonator, a first nonlinear optical element (NLO) and a second non-linear optical element (NLO). The first NLO can produce, via OPO of a first pump beam, a first output with a first frequency and a second output with a second frequency. The second frequency is lower than the first frequency. The second NLO can produce, via OPO of a second pump beam (with a higher frequency than the first), a third output with a third frequency and a fourth output with a fourth frequency. The fourth frequency is lower than the third frequency. The first frequency is the same, or at least substantially the same, as the fourth frequency. The OPO device is configured to resonate at the first frequency and the fourth frequency.

Abstract: Tunable light sources having a single optical parametric generation (OPG) source that results in an amplified, narrow bandwidth seed beam and methods of tuning therewith are disclosed. The tunable light source may include a polarization rotator to rotate a pump beam before a first pass through an OPG, and a linear-to-circular polarization device to polarize the pump beam directed back toward the OPG for a second pass therethrough. Alternately, the tunable light source may include an OPG source through which a pump beam passes only in the first direction, a separator that separates a signal beam from the pump beam exiting from the OPG, a narrowband wavelength filter that receives the signal beam and generate a seed beam, and a reflecting surface that directs the seed beam back through the OPG (opposite the first direction) to seed the back part of the pulse of the pulse laser.
