Chirped acousto-optic Q switch
Patent
·
OSTI ID:6484074
An improved acousto-optic laser Q-switch utilizing a chirped fm pulse in the acousto-optic cell to diffract and focus the input beam into a resonating high-Q mode is described. When the rf acoustic pulse is not wholly within the cell the beam is diverted to the output. A reflective surface is placed on the cell to yield only one output beam and to yield a retroreflective beam back into the cavity for a high Q condition whenever a correctly generated chirp acoustic wave is in the proper position within the cell.
