Abstract

The Degenerate Optical Parametric Oscillator (DOPO) is a device which is capable of producing complicated spatial emission profiles distinct from the usual axial Gaussian beam. This oscillator can be forced into emitting off axis, which due to the nature of the conversion results in two spatially dislocated beams. These beams interfere within the oscillator cavity, with the resulting pattern known by the name “Roll Pattern”^[1].
