An optical parametric oscillator (OPO) is a parametric oscillator that oscillates at optical frequencies. It converts an input laser wave (called "pump") with frequency into two output waves of lower frequency ( ) by means of second- order nonlinear optical interaction.

An optical parametric oscillator (OPO) [1, 2] is a light source similar to a laser, also using a kind of laser resonator, but based on optical gain from parametric amplification (usually in a nonlinear crystal) rather than from stimulated emission of radiation.

Optical parametric oscillators are versatile devices for generating a tunable coherent radiation from an incident laser beam. They rely on nonlinear frequency conversion to cover spectral ranges that are poorly or not covered by direct laser emission.

Optical parametric oscillators (OPOs) are convenient sources of coherent light that suit numerous scientific applications, including various types of spectroscopy, multiphoton excitation, and...

In this Chapter we will discuss an optical parametric oscillator. A parametric oscillator is almost like a laser. The difference is that the optical gain inside the cavity comes not from a population inverted medium but from a nonlinear optical medium which possesses either the second order ( 2 ) or the third. order ( 3 ) optical nonlinearity.
