Abstract
An optical parametric oscillator which operates with uncoated optics and a non-linear crystal. The pulse length is long relative to the cavity length, and hence the pump is still operating when the crystal flouresces. The fresnel reflection from the uncoated optics is sufficient to maintain the flouresence. Another aspect attenuates one of the idler and signal beams within the cavity, to allow the other one to emerge more dominant.
