高空逆溫-
The second part is about co2 lasers. we first discuss the mechanisms of population inversion, including excitations and relaxations ( electron collision excitation, resonance transition excitation impacted by excited n2 molecules, the relaxation of both the lower - upper laser levels and the lowest level of co2 )
首先,討論了二氧化碳激光粒子數的反轉機理,包括電子碰撞激勵、激發態n2分子等共振轉換激勵過程,激光上下能級co2 ( 00 1 , 10 0 )以及最低能級co2 ( 0110 )的弛豫過程等幾個方面
