ABSTRACT:
An optical parametric oscillator (50) includes a resonator cavity (26) for laser light, and a gain medium (28) disposed in the resonant cavity for converting pump light to the laser light. The oscillator includes an optical arrangement for directing a pulse of the pump light pulse to make generally axially counterpropagating initial and return passes through the gain medium. The optical arrangement includes a pulse return reflector (37) for directing the pulse to make the return pass. The reflector is separated from the gain medium forming a delay line of length sufficient that the initial and return passes are separated in time by greater than about 0.5 FWHM of the pump light pulse. The reflector forms part of a relay imaging system (51) which causes the initial and return passes to propagate through substantially the same volume of gain medium.
