Theoretical Numerical Simulation of Acousto-optic Q-switching CO2 Lasers with a Four-energy-level Model
Acousto-optic Q-switching CO2 lasers are widely used in laser ranging,production and processing,space communication,spectroscopy,environmental detection,and radar imaging fields due to their ideal transmission efficiency at specific wavelengths,good beam focusing performance,high continuous power,and large output pulses.This paper presents a rate equation for an acousto-optic Q-switching CO2 laser based on a four-energy-level model considering acousto-optic losses.Under certain conditions,the rate equation set is numerically simulated through discrete iterations,and the operating characteristics of the acousto-optic Q-switching CO2 laser are analyzed to better use and design CO2 lasers in production research.
