Optical parametric oscillator pumped at ~1 µm with intracavity mid-IR change-frequency generation in OPGaAsIt has prolonged been predicted that the stage distinction between the signal and idler subharmonic outputs of an optical parametric oscillator (OPO) undergoes a random stroll system, much like the period diffusion of the laser [1].This metho
