Source Of Ultraviolet Light Employing A Laser Pumped Borate Crystal
US Patent:
3934154, Jan 20, 1976
Filed:
Feb 18, 1975
Appl. No.:
5/550526
Inventors:
William R. Cook - Cleveland Heights OH
International Classification:
G02F 137
US Classification:
307 883
Abstract:
This invention pertains to an ultraviolet light generator which mixes, or frequency doubles, light by means of a borate crystal such as AB. sub. 5 O. sub. 8. 4H. sub. 2 O where A=Ammonium (NH. sub. 4), Potassium (K), Rubidium (Rb), or Cesium (Cs). This ultraviolet light generator is pumped with a dye laser capable of emitting coherent light of wavelengths from 4000 to 5600 A (Angstroms) to generate phase matched second harmonics between about 2150 A and 2650 A, a range not readily attained by systems using other crystals.
