  • Source of ultraviolet light employing a laser pumped borate crystal
    Patent number: 3934154
    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.
