  1. 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
  2. With time - evolution - operator, it is proved that the population of upper level is in circumstance of cyclic oscillation by laser pulses pair of gaussian line - shape in a homogeneous broadening two - level system. the oscillatory time oxide is the delay time between the laser pulse pairs and the oscillatory frequency equals the one of transition between the lower and upper level

    引入時間演化算符，證明均勻增寬二能級體系在飛秒激光脈沖對作用下上能級激發態布居是周期性變化的，它以飛秒脈沖對之間的延時為時間軸，以該原子能級之間的躍遷頻率為振蕩頻率
