Study and development of an all-solid state pulsed picosecond YAG laser optimized for optical pumping of optical parametric oscillators tunable in IR and visible spectral ranges

Development of a pulsed YAG laser, mode locked, using a frequency doubling non linear mirror as active feedback and a GaAs platelet as passive negative feedback. The non linear mirror consists of a BBO crystal and a dichroïc mirror. The laser source pump on OPO picosecond used for ir-vis sum frequency generation spectroscopy.
