An optical parametric oscillator is a parametric oscillator that oscillates at optical frequencies. It converts an input laser wave with frequency ω p into two output waves of lower frequency by means

Nonlinear optics is a branch of optics that studies the case when optical properties of matter depend on the intensity of the input light. Nonlinear phenomena become relevant only when the input light
Optical parametric oscillator
…It converts an input laser wave (called "pump") with frequency ω p into two output waves of lower frequency ( ω s , ω i ) by means of second-order nonlinear optical interaction. The sum of the output waves' frequencies is equal to the input wave frequency: ω s + ω i = ω p . For historical reasons, the two output waves are…
