Аннотация:We have observed efficient multiphoton excitation of CH3OH molecules by broadband pulsed YSGG:Cr:Er laser radiation (wavelength 2.7um, pulse duration 60ns, bandwidth 1.5cm^-1) at fluence of 0.3-600J/cm2 under collision and collisionless conditions. Multiphoton dissociation of CH3OH has been realized. We discuss the role of intermode interaction, the intensity of the laser radiation, and the laser bandwidth in the excitation process.
