International audience; Coherent beam combining (CBC) by active phase control could be useful for power scaling fiber-laser-pumped optical frequency converters like optical parametric oscillators (OPOs). We developed an indirect phase control approac

International audience; We report what is, to the best of our knowledge, the first experimental demonstration of coherent combining of two mid-infrared difference frequency generators by active phase control in continuous-wave regime. Using the phase

This thesis reports on a detailed characterization of the second harmonic generation (SHG) responses of indolino-oxazolidine derivatives in different environments. These molecular switches are particularly interesting because they can commute between

International audience; We investigate the effect of gamma radiation on flux grown KTiOPO 4 and Rb:KTiOPO 4 samples, as well as their periodically poled variants. Specifically, we study the altered transmission due to color-center formation via gamma

International audience; We investigate and model a picosecond synchronously pumped optical parametric oscillator (OPO) based on an aperiodically poled lithium niobate (APPLN) nonlinear crystal with a chirped quasi-phase-matching (QPM) grating. We obs
