Abstract
A waveguide gas laser is disclosed wherein narrow resonances in the loss vs. wavelength characteristics of a hollow waveguide laser resonator are employed to achieve wavelength selectivity. The laser includes a capillary bore waveguide of radius a and length 2L (or length L in a half-symmetric arrangement) which contains a laser gas having a laser transition capable of providing stimulated emission of light at wavelength .lambda.. The aforementioned loss resonances are achieved when the waveguide dimensions and the wavelength .lambda. are of preselected values satisfying the relation ##EQU1## where N is a positive integer.
