Cerium Activated Colquirite Laser Crystal

US Patent:
5852623, Dec 22, 1998
Filed:
Oct 25, 1996
Appl. No.:
8/736158
Inventors:
Vida K. Castillo - Tarpon Springs FL
Gregory J. Quarles - Tarpon Springs FL
Arlete Cassanho - Palm Harbor FL
Wayne R. Ignatuk - Crystal Beach FL
Assignee:
VLOC, Incorporated - New Port Richey FL
International Classification:
H01S 316
US Classification:
372 41
Abstract:
A laser crystal for a solid state laser with tunable emission in the ultraviolet wavelength region. The crystal is of trivalent cerium cations activated (doped) into the colquiriite crystal structures, such as LiCaAlF. sub. 6 (LiCAF) and LiSrAlF. sub. 6 (LiSAF). The crystal is grown along a well-defined axis by seeded crystal growth techniques to provide starting material which is fabricated along the preferred polarization direction with high yields. A primary crystal growth issue for cerium activated colquiriites is the charge compensation mandated by the substitution of the trivalent cerium ion for divalent strontium, which is located in the only site large enough to support the cerium cation. Charge compensation with monovalent or divalent cations is utilized to optically stabilize the colquiriite crystal and produce a solid state laser host which is less susceptible to color center or optically-induced defect formation during the ultraviolet lasing or ultraviolet excitation mechanisms.
