ABSTRACT:
A new class of high-power lasers capable of high efficiencies in the visible and shorter wave lengths is taught, employing an excitation energy transfer mechanism from a pumped noble donor gas, such as Argon, to an acceptor lasing gas, preferably Nitrogen. In particular, such an Argon/Nitrogen laser exhibits a very useful, unique output wave length at 3577A, this being derived from a mixture of Argon, predominantly, with a minor percentage of Nitrogen, excited by a relativistic electron beam of relatively high current density. Such gas lasers with a noble gas as donor offer great promise, using high electrical conversion. efficiency of the noble donor gas with a non-radiative energy transfer to the lasing gas.
