Investigation of Terbium in the Ferroelectric Crystal, Gadolinium Molybdate,as a Potential Laser.

摘要

A preliminary non-stimulated study of the laser host combination Gd(2 - x) Tb(x)(MoO4)3is made. The host material,gadolinium molybdate (GMO),is a ferroelectric/ferroelastic crystal. An investigation of temperature and external electric field affects on the absorption and fluorescence of the crystal did not produce any unusual results. The terbium ion,Tb(3+),peak cross section in GMO for the 5D sub 4to 7F sub 5transition is 10 x 10to the minus twenty first power sq. cm. at 300K. The wavelength of this four level laser transition is 543nm.
