CROSS-DOPING AGENTS FOR RUTILE MASERS
WESTINGHOUSE ELECTRIC CORP PITTSBURGH PA
Pagination or Media Count:
Tantalum and niobium appear to be suitable crossdoping agents for securing a short spin-lattice relaxation time in masers using rutile as the host crystal. Initial tests on rutile doped with chromium and tantalum are encouraging. Cerium does not appear to enter rutile as Ce3. Departure from stoichiometry, although it results in a spectrum with short spin-lattice relaxation time, presents the problem of non-frequencyselective cross-relaxation.
