Review of CW high-power CO 2 lasers
TL;DR: The CO 2 laser can exhibit a wide range of noise, bandwidth, gain, and power saturation characteristics depending on the gas pressure, gas flow rate, pumping mechanisms, gas mixture, etc as discussed by the authors.
Journal ArticleDOI
High-pressure pulsed molecular lasers
TL;DR: A review of recent developments in high-pressure pulsed molecular lasers is presented in this paper, which includes some experimental results on TEA lasers, E-beam lasers, and lasers using Blumlein excitation.
Journal ArticleDOI
Pulsed CO2 Gas‐Dynamic Laser
TL;DR: In this paper, a pulsed combustion-operated CO2 gas-dynamic laser was used to simulate CO2 and N2 expansion in a combustion chamber, where the mixture expands through a supersonic nozzle, thereby causing population inversion in CO2.

Gain of co2 gasdynamic lasers
George P. Lee,Forrest E. Gowen +1 more
TL;DR: In this article, experimental measurements and theoretical calculations of gain for a cw CO2 gasdynamic laser were made for a CO2, N2, He mixture, at a temperature range of 800 to 2000°K, pressure range of 2 to 16 atm, and a complete range of gas mixtures.

LASER POWER AT 5 μm FROM THE SUPERSONIC EXPANSION OF CARBON MONOXIDE
TL;DR: In this article, the supersonic expansion of CO in mixtures of N2 and Ar was studied and the ratio of laser power to the total enthalpy flow rate supplied to the nozzle reservoir was equal to or greater than that obtained from similar CO2 gas-dynamic lasers.

Electronic Population Inversions by Fluid‐Mechanical Techniques
I. R. Hurle,A. Hertzberg +1 more
TL;DR: In this article, the promotion of population inversions between electronic excited states by fluid-mechanical techniques is suggested, and three methods are proposed as illustrations, and the possible degree of inversion in each is estimated.

Nitrogen laser action with supersonic flow
Jack Wilson,Arthur Kantrowitz +1 more
TL;DR: Lasing action is electrically induced in a supersonic flow of nitrogen gas, resulting in an increase in pulse repetition rate to a new order as mentioned in this paper. But this is not the case in our case.
