Apparatus And Method For Longitudinal Diode Bar Pumping Of Solid State Lasers

View page
US Patent:
51396092, Aug 18, 1992
Filed:
Feb 11, 1991
Appl. No.:
7/654430
Inventors:
Renny A. Fields - Los Angeles CA
Todd S. Rose - Long Beach CA
James S. Swenson - El Segundo CA
Assignee:
The Aerospace Corporation - El Segundo CA
International Classification:
H01L 21306
B44C 122
H01S 319
US Classification:
156643
Abstract:
The invention is a solid state laser resonator or amplifier which employs a longitudinal pumping scheme that provides efficient coupling of greater than 90 percent from the output of one or more high power diode bar arrays. The pumping scheme involves the use of monolithic microlens arrays that match the geometry of the laser diode bar arrays in a one to one manner. The output of each element in the diode bar is collimated by a single microlens in the array. The resultant array of collimated light beams is then configured to overlap by a second macroscopic lens, resulting in a single uniform spot within the laser gain medium. The resultant spot is also configured to overlap with the TEM. sub. 00 mode of the laser resonator so that efficient lasing action may occur. Overlapping the pump spot and the laser mode may be interpreted as having the pump spot size be less than or equal to the laser mode size so that all the pump light is absorbed within the mode of the laser.
