An optical parametric device, for example an optical parametric generator or amplifier or oscillator, comprising a non-linear material (13) that is operable to generate a signal and an idler wave in response to being stimulated with a pump wave. The non-linear medium is such that the pump and idler waves are substantially collinear and the signal wave is non-collinear. L'invention concerne un dispositif paramétrique optique, par exemple un générateur, un amplificateur ou un oscillateur paramétrique optique, qui comprend un matériau non linéaire (13) conçu pour générer un signal et une onde idler en réponse à une stimulation par une onde de pompage. Le milieu non linéaire est tel que les ondes de pompage et idler sont sensiblement colinéaires et que l'onde de signal est non colinéaire.
