Sv. Kukhlevsky et L. Kozma, DIFFRACTION-LIMITED TRANSVERSE-COHERENT RADIATION OF PULSED CAPILLARYGAS-LASERS WITH WAVE-GUIDE RESONATORS, Optics communications, 122(1-3), 1995, pp. 35-39
The spatial distribution and coherence of pulsed radiation generated i
n capillary gas lasers with optical feedback implemented by waveguide
resonators with external mirrors have been analyzed. A waveguide reson
ator configuration has been developed which provided near diffraction-
limited transverse-coherent radiation of a short-pulse waveguide N-2-l
aser.
