The present invention comprises an optical parametric oscillator for down-conversion of coherent light to longer wavelengths. The present invention comprises an optical pump source for providing a pump beam at a primary wavelength. The pump source is coupled into a singly-resonant cavity through an input mirror positioned at the input end of said cavity. The inputed pump beam is directed into a monolithic non-linear optical medium having multiple regions formed on a single substrate. An optical parametric oscillation occurs at each stage of the optical medium; however, the signal (resonated) frequency is identical at each stage of the optical medium. The single frequency produced at each stage of the optical medium results in a sequential gain of the signal, which is resonated by an output mirror which is adapted to reflect and oscillate the signal frequency within the cavity, and allow the idler frequency to pass through the cavity.

[ What is claimed is:] [12.]12. An optical parametric oscillator for down-conversion of coherent light to longer wavelengths comprising:(a) an optical pump source for providing a pump beam at 1.064 .mu.m;(b) a singly-resonant cavity having an input end and an output end;(c) a monolithic non-linear optical medium disposed in said cavity comprising seven regions formed on a single substrate for sustaining optical parametric oscillation by producing an identical resonated signal frequency of 8.5 .mu.m and a resultant idler frequency at each stage of the optical medium resulting in sequential gain of the resonated signal;(d) a reflective and transmissive input mirror positioned at the input end of said cavity, for coupling the pump beam into the resonant of cavity and through the monolithic non-linear optical medium; and(e) a reflective and transmissive output mirror positioned at the output end of said cavity, adapted to couple the idler frequency out of the cavity, and further adapted to partially reflect and to oscillate the signal frequency within the resonator cavity.
