Electro-optic harmonic conversion to switch a laser beam out of a cavity

Patent Haas, Roger A. ; Henesian, Mark A.

The invention is a switch to permit a laser beam to escape a laser cavity through the use of an externally applied electric field across a harmonic conversion crystal. Amplification takes place in the laser cavity, and then the laser beam is switched out by the laser light being harmonically converted with dichroic or polarization sensitive elements present to alter the optical path of the harmonically converted laser light. Modulation of the laser beam can also be accomplished by varying the external electric field.

Fast acousto-optic q-switch laser

Patent - in OSTI.gov collection Ellis, F.E.

A fast acousto-optic q-switch laser is taught comprising a lasing medium, reflecting means mounted substantially perpendicular to the longitudinal axis of the lasing medium and spaced from a first end thereof, feedback reflecting means spaced from a second end of the lasing medium, optical pumping means for pumping the lasing medium, an acousto-optic switch mounted along and tilted at a preselected angle with respect to the longitudinal axis of the lasing medium between the second end of the lasing medium and said feedback reflecting means and spaced from the second end of said lasing medium for deflecting a portion ofmore »« less

Chirped acousto-optic Q switch

Patent - in OSTI.gov collection Jernigan, J.L.

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.

Multiple switch actuator

Patent Beyer, Edward T.

The present invention relates to switches and switch actuating devices to be operated for purposes of arming a bomb or other missile as it is dropped or released from an aircraft. The particular bomb or missile in which this invention is applied is one in which there is a plurality of circuits which are to be armed by the closing of switches upon dropping or releasing of the bomb. The operation of the switches to closed position is normally accomplished by means of a pull-out wire; that is, a wire which is withdrawn from the bomb or missile at themore »« less
