Birefringence phase matching

A technique for maintaining constructive non-linear interaction during propagation in non-linear material by playing on the material's birefringence to compensate for the deleterious effect of chromatic dispersion.

Optical parametric amplifier; Amplificateur paramétrique optique

A device comprising one or more non-linear quadratic crystals on which intense pump radiation and longer-wavelength radiation are incident, enabling amplification of said incident longer-wavelength radiation by optical parametric effect.

Oscillateur paramétrique optique; optical parametric oscillator

A device comprising an optical parametric amplifier inserted in an optical resonator which generates wavelength-tunable coherent radiation from pump laser radiation...
