Abstract
A low-finesse, tri-etalon optical parametric oscillator includes an optical cavity bounded by two coupling mirrors, and a narrow-linewidth pump laser which supplies pump energy to the optical cavity at a pump wavelength. A pair of walk-off compensated, non-linear optical crystals (but not limited to walk-off compensated) is disposed with the cavity and converts energy at the pump wavelength to energy at longer signal and idler wavelengths. The mirrors are configured such that each of the three beams (pump, signal and idler) is approximately 70% to 100% reflected at one end of the cavity and approximately 10% to 30% reflected at the other end of the cavity. This configuration causes partial resonance of each of the beams and generates an etalon effect which enhances the fluence in the leading and trailing edges of pulses in the cavity, thereby enhancing the energy conversion efficiency from the pump wavelength to the signal and idler wavelengths.
