Definition of "optical parametric oscillator" |
a nonlinear optical device that can produce a frequency tunable output when pumped by a fixed frequency laser beam. The device consists of a second-order nonlinear optical crystal placed inside of an optical resonator as well as additional components for precise control of the output characteristics. When pumped by a laser beam at the pump frequency ωp, it produces two output frequencies, one at the signal frequency ωs and one at the so-called idler frequency ωi , where ωp = ωs + ωi . |
