Decreasing the divergence of high-gain lasers
TL;DR: In this paper, a simple method of reducing the divergence of high gain laser by placing an anamorphic prism beam expander in the cavity is described, which can be used in excimer and copper vapour lasers as well.

Analysis of a noncavity laser with magnifying optics in front of the high-reflectivity mirror
TL;DR: In this article, the behavior of a noncavity laser with a magnifying optical element placed in front of the high-reflectivity mirror is analyzed using ray matrix analysis, and a general formula for estimating the divergence is derived.

Coherent radiation from a nitrogen laser
TL;DR: In this paper, a spatially coherent oscillator at 337 nm was made by placing a nitrogen discharge inside an unstable resonator of high magnification, achieving an energy of 205 μJ with 100 μJ in a diffraction-limited spot.
Journal ArticleDOI
Coherent uv from a TEA N2 laser system
TL;DR: In this paper, a technique was described to couple and synchronize two transversely excited atmospheric (TEA) nitrogen lasers in an oscillator-amplifier configuration to obtain spatially coherent 1nsec pulses at 337 nm with an energy/pulse of several hundred microjoules.
Journal ArticleDOI
Single-frequency emission from a nitrogen laser
TL;DR: In this article, single-frequency stimulated emission was obtained from a selective resonator of a nitrogen laser operating in the super-radiance regime, where the stochastic structure of the spectrum was destroyed and the emission at the external-signal frequency.
