Dynamics of the Pulsed Intracavity OPO

We have studied the dynamical properties of the OPO when it is inserted into the pump laser cavity. The temporal evolutions of the population inversion, pump and signal intracavity powers are modelised by a simple system of coupled equations. Numerical simulations show that the OPO can produce one or severa1 pulses depending on the signal cavity finesse and the pumping level of the laser medium. The energy transfer from the laser medium to the signal pulses can be very efficient.
