We report on first nonlinear mirror mode-locked praseodymium based solid-state laser. As an active medium, the Pr:YAlO 3 crystal was used. For mode-locking, a nonlinear BBO crystal together with a properly designed dichroic mirror were employed to fo

A high conversion efficiency and stability are the anticipated advantages of intracavity pumped parametric oscillators, as opposed to the traditional externally pumped ones. The dynamics of the coupled pump and signal cavities, however, is very compl

The operation of a picosecond synchronously intracavity pumped optical parametric oscillator (OPO) is reported. A magnesium doped lithium niobate crystal (MgO:PPLN), periodically poled, is used as the optical parametric oscillator crystal coupling th
