Technique For Electronically Stabilizing The Ouputs Of Acoustooptic Devices
US Patent:
5742425, Apr 21, 1998
Filed:
Jan 23, 1997
Appl. No.:
8/789316
Inventors:
John Kump - Hillsborough CA
Arron Campi - San Jose CA
Arron Campi - San Jose CA
Assignee:
Crystal Technology, Inc. - Palo Alto CA
International Classification:
G02F 111
US Classification:
359285
Abstract:
A technique of stabilizing the output of an acoustooptic modulator. A laser passes a light beam through the acoustooptic modulator. A driver circuit connects to a drive electrode of the acoustooptic modulator. RF generators deliver drive power at a first carrier frequency and compensation power at second and third carrier frequencies, one higher and the other lower than the first carrier frequency. The driver circuit modulates the drive power and the compensation power such that compensating acoustic energy induced in the acoustooptic modulator complements drive acoustic energy, and the spatial content of the drive acoustic energy. The combined drive power and the complementing compensating power maintain the spatial thermal energy distribution inside the acoustooptic modulator substantially constant. Consequently, beam steering and thermal ellipticity are stabilized and remain substantially constant throughout the operating range of the modulator.
