A parametric device having a non-linear material (4) for generating an idler wave and a signal wave (16) in response to a pump wave (14), the pump, idler and signal waves being non-collinear, the device having a cavity (10, 11) resonant at the pump wavelength and means for varying the angle between the propagation directions of the pump and idler waves. Dispositif paramétrique comportant un matériau non linéaire (4) servant à générer une onde idler et une onde signal (16) en réponse à une onde pompe (14), les ondes pompe, idler et signal étant non colinéaires, le dispositif comportant une cavité (10, 11) résonnant à la longueur d~onde pompe et un moyen servant à faire varier l~angle entre les directions de propagation des ondes pompe et idler.
