High-power double-discharge TEA laser medium diagnostic

We have studied the spectral behavior of the gain of a high-pressure transversely excited CO
2
laser that delivers an output energy of 40 J/1 within about 1 μs and 20 J/1 within 70 ns. From these data we found the translational temperature of the amplifier medium,
T = 435
K and the vibrational temperature of the ν
3
mode,
T_{3} = 2750
K.
