The former corresponds to the thermo-stableresonator for steady mode;
前者对应于稳模式热稳腔；

The ABCD matrix of an active resonator has been deduced, and the conditions of the stableresonator and the thermal-insensitive laser output mode have been discussed.
推导出有源谐振腔abcd传输矩阵，讨论了谐振腔稳定性条件和输出模式的热稳定性条件。

Comparing with traditional stableresonator high-power TEA CO2 laser, it is always the key point to improve the optical beam quality as the same time guarantee the power of laser.
