Numerical investigations of energy characteristics of the first overtone generation of a high-power supersonic e-beam-sustained CO laser

Abstract

For operating conditions of the high power supersonic e-beam sustained CO laser a numerical investigation of the energy and spectral characteristics of the first overtone generation is conducted. It is shown that electro-optical efficiency of the first overtone generation can be more than 30%. The efficiency of a spectrum selection both on fundamental and first overtone transitions is evaluated. On the basis of numerical calculations the engineering evaluations for several variants of such a device are executed.

Laser Propulsion Market-Creating Innovation

“…[10][11][12] While construction of the full-scale 1 MW average power technological supersonic CO laser prototype (further referred to as CODL) is still in progress, the theoretical research produced the mathematical modeling and simulations of the CODL operation in CW and Q-switched modes, followed by the plausible estimates of its operation under various conditions, including the multi-MW laser design. [13][14][15][16][17] By the wide scope of its technological capabilities, CODL can be classified as a key enabling technology.…”

Ground based laser triggered discharges on satellite solar arrays

“…CW and pulsed CO lasers can be doubled to wavelengths between 2.5 and 4.2 µm. 41 The LOK Co. (Russia) offers a 200-kW CO laser that can be doubled with ~ 30% efficiency 42,43 . JSC Energomashtechnika also sells "diffraction-limited" 5-kJ CO 2 lasers and "mobile," "diffraction-limited" 100-kW CO 2 lasers § .…”
