Beschreibung
Zusammenfassung:	An optical parametric oscillator includes one unidirectional enhancement resonator for optical pump-radiation and a second unidirectional resonator at least partially coaxial with the enhancement resonator. An optically nonlinear crystal is located in the coaxial portion of the resonators and converts the optical pump-radiation to signal radiation having a wavelength longer than that of the pump radiation and idler radiation having a wavelength longer than that of the signal radiation. The second resonator resonates the signal-wavelength radiation and delivers a fraction of that radiation as output radiation.
