Abstract
A pulsed optical parametric oscillator comprising a spectrally pure source or emitting pumping wave pulses, a non-linear crystal to which the pumping wave is applied, a resonant cavity for the complementary wave defined by two same-axis mirrors situated on opposite sides of the crystal, a cavity for the signal wave defined by two same-axis mirrors situated on opposite sides of the crystal, and means for adjusting the length of one or both cavities, wherein the oscillator is a monomode pulsed parametric oscillator and wherein one of the two mirrors for each cavity is situated between the two mirrors of the other cavity.
