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(shù)的反轉(zhuǎn)機理，包括電子碰撞激勵、激發(fā)態(tài)n2分子等共振轉(zhuǎn)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
Since the carrier mobility in organic materials is very low , no collision excitation is possible . the short wavelength peak is due to direct bombardment by electrons from sic > 2 . we name this luminescence as cathodoluminescence - like ( cl - like ) emission or solid state cathode luminescence because the energized electrons are accelerated in solid instead of in vacuum
這樣在有機層中的電子數(shù)是nl n計n汁n ，空穴數(shù)是p n （ n是類陰極射線激發(fā)出的電子，也是類陰極射線激發(fā)出的空穴兒這兩類載流子的復合將比單純有機發(fā)光的復合nip增加了（ n計n葉n ）叮（ l n計n葉n ） n 。
