Programmable pulse shaping for optimized laser interactions

Summary form only given. We have developed Q-switched lasers which function as arbitrary pulse shapers. We apply the effect of "dynamic mirrors" by temporally varying the cavity Q as the laser rod is pumped (i.e. effectively varying the output coupling). Hence, the energy storage in the rod and the intracavity intensity can be controlled. This allows temporal shaping of the laser pulses with intracavity elements. We have built and tested both acousto-optic and electro-optic pulse shapers. Both systems are based around quasi-CW diode-pumped Nd:YLF systems.
