ABSTRACT:
The problem of the low efficiency of large quantum defect optical parametric oscillators is solved by recycling unused photons in a process involving pumping additional parametric processes having a common resonant wavelength. In order to improve the efficiency, a series of optical parametric oscillators are pumped with unused signal photons which exist at the output of a previous optical parametric oscillator that generates both signal and idler outputs, with the idler constituting the desired output.
