Abstract
Abstract Several gas-tight enclosures share a common optical cavity. The enclosures may be filled with neat gases or mixtures of gasses. The same gas or mixture, at the same or a different pressure, may occur in more than one enclosure. The gas or gasses in the various enclosures may be pulsed to lase in any desired sequence, simultaneously, or in any combination.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
55 words
A multiple-section pulsed gas laser consisting of an optical cavity with an optical axis therein, a plurality of gas tight enclosures colinear to said axis, a gaseous material capable of lasing in each of said enclosures, and individual selectable means for pumping the material in a respective enclosure to cause lasing of the material therein.
Claim 2
Dependent Claim
