  • The output energy of a pulsed TEA CO2 laser versus the ambient temperature -30℃～+60℃ was calculated out by six-temperature mode rate equations.Numerical result shows that the output pulse energy almost decreases linearly with the ambient temperature.The gradient of the pulse energy to ambient temperature varies with the composition of the laser mixtures,pressure,mirror reflectance or input energy.With higher mixture pressure,mirror reflectance,or input energy,the output pulse energy decreases more quickly with the ambient temperature.

Abstract: The output energy of a pulsed TEA CO2 laser versus the ambient temperature -30℃～+60℃ was calculated out by six-temperature mode rate equations.Numerical result shows that the output pulse energy almost decreases linearly with the ambient temperature.The gradient of the pulse energy to ambient temperature varies with the composition of the laser mixtures,pressure,mirror reflectance or input energy.With higher mixture pressure,mirror reflectance,or input energy,the output pulse energy decreases more quickly with the ambient temperature.
