ABSTRACT:
An optical parametric oscillator includes a pump laser for producing a pump beam, an optical resonator, an OPO crystal disposed within the optical resonator aligned with and responsive to the pump beam to produce a parametrically generated output, and a device external to the optical resonator for line narrowing the parametrically generated output. In one embodiment of the invention, the device is a grating and in another embodiment of the invention the device is an acousto-optic cell.
