Un OPO est un oscillateur laser o\u00f9 le gain ne d\u00e9pend pas d\u2019une inversion de population atomique ou mol\u00e9culaire entre deux niveaux d\u2019\u00e9nergie, mais d\u2019une condition d\u2019accord de phase (phase-matching) liant l\u2019onde \u00ab pompe \u00bb (de fr\u00e9quence angulaire \u03c9p) et les deux ondes param\u00e9triquement g\u00e9n\u00e9r\u00e9es (onde \u00ab signal \u00bb de fr\u00e9quence \u03c9s et \u00ab compl\u00e9mentaire \u00bb ou idler de fr\u00e9quence \u03c9i) par le couplage non lin\u00e9aire \u03c7(2) (susceptibilit\u00e9 non lin\u00e9aire d\u2019ordre 2) du mat\u00e9riau de gain (fig. 1ab) [8]. Dans une conversion param\u00e9trique de fr\u00e9quence, la conservation de l\u2019\u00e9nergie du photon pompe est respect\u00e9e (\u03c9p = \u03c9s + \u03c9i, fig. 1d).
