Book Description
Laser sources generating sub-nm radiation, using recoilless nuclear transitions in solids, have been proposed for years. This review examines, from the standpoint of kinetics, many solutions (viz., narrowed line, explosive neutron pump, two-stage pump, two-step pump) that have been proposed for the basic problem: that pumping can inhibit or destroy the Moessbauer and Borrmann effects, which are essential for gain. 4 refs.

Book Description
Gamma-ray lasers, although proposed for many years, remain undeveloped because pumping can destroy conditions essential for gain. We review many of the solutions (viz, narrowed-line, explosive neutron pump, two-stage pump, two-step pump) proposed so far, with emphasis on kinetics. The most promising approach requires fast interlevel transfer from a separated isomer to initiate a superradiant Borrmann mode in a solid host. However, suitable nuclear transitions and nondestructive transfer mechanisms have yet to be identified.

Languages : en
Pages : 166
Book Description
Provides a definitive overview of the current status of gamma-ray lasers including contributions from scientists pursuing active research in areas relevant to the graser problem. Describes a range of programmes which deal with selecting candidate nuclei, procuring the right lasing medium and forming it into an acicular geometry, working in an energy regime that enables utilizing the Mossbauer Effect, using the Campbell-Borrmann Effect to decrease electronic absorption, designing basic experiments that demonstrate critical steps necessary to produce a graser, and clarifying a number of theoretical problems specific to the nuclear laser.

Study of a Nuclear Gamma-Ray Laser
Author: Richard L. Liboff
Publisher:
ISBN:
Category :
Languages : en
Pages : 16
Book Description
In this analysis we describe briefly a possible approach to the realization of a gamma-ray laser ('graser') 1,2. The proposed scheme has its basis in certain long-lived excited states among the heavier nuclei. Decay of such states, for the most part, gives rise to high-order multipole radiation. These excited states are populated through either beta-decay or electron capture. The device presumes that a collection of such long-lived excited states is unstable to induced resonant emission. Decay of parent nuclei serve as the pumping mechanism in the proposed lasing scheme. (Author).
