Overview

Simulation study demonstrates an electron density threshold governing power degradation in electron-beam controlled TEA-CO2 lasers, suggesting critical parameters for laser design.

Key Points

To establish a theoretical framework that models collision-induced current effects and evaluates the dynamic power characteristics of electron-beam controlled TEA-CO2 lasers.
Derived a discharge current equation incorporating electron collisions with laser gas molecules.
Integrated the collision-induced current equation into a discharge circuit model and a six-temperature model (6TM) to simulate dynamic laser emissions.
Validated the model against published experimental emission data and evaluated laser power output across varied initial electron densities.
Dynamic emission profiles calculated by the theoretical model closely matched benchmark experimental measurements.
Laser power output degraded significantly once the initial electron density exceeded a distinct critical threshold.
