Acousto-Optic Cavity Dumpers / Pulse Pickers


The Brimrose Free Space Cavity Dumper is typically used in a mode-locked laser cavity to separate a single optical pulse from the pulsed energy circulating. As a result, nearly all the laser energy is dumped out of the resonant cavity in the form of a single optical pulse. A cavity-dumper offers high peak power and higher repetition frequencies.
