Line 1: [[Image:IR Optical Parametric Oscillator.JPG‎\|thumb\|300 px\|right\|Infrared optical parametric oscillator]] An '''optical parametric oscillator''' (OPO) is a [[parametric oscillator]] which oscillates at optical frequencies. It converts [[second order]] [[nonlinear optics\| nonlinear optical interaction]]. The sum of the output waves frequencies is equal to the input wave frequency: <math>\omega_s + \omega_i=\omega_p</math>. For historic reasons, the two output waves are called "signal" and "idler", where the wave with ~~bigger~~higher frequency is called signal. A special case is the degenerate OPO, when the output frequency is one-half the pump frequency, <math>\omega_s=\omega_i=\omega_p/2</math>. == Overview ==
