• In chapter 3 , we studied the effect of gaussian transverse profile for the driving and laser fields on lasing without population inversion ( lwi ) in a closed v - type system and an open v - type system . moreover , we discussed also the effect of the unsaturated gain coefficient , the cavity - damping rate , the ratio of the atomic injection rates and atomic exit rate on the corresponding systems . in chapter 4 , we mainly discussed the effect of doppler broadening on the gain , dispersion and the frequency up - conversion of the open v - type lwi system and compared the differences and the same between the open system and the corresponding closed system
  发现： ( 1 )在考虑doppler展宽的情况下，通过选取合适的实验室条件(比如合适的原子环境温度等)可得到合适doppler展宽值，从而使系统获得最佳增益； ( 2 )要想实现系统的频率上转换，同时又要获得足够强的无反转激光增益，则系统频率转换比不能选取的太大； ( 3 )对于开放系统，比较小的粒子注入速率比与退出速率对产生无反转激光是有利硕士学位论文摘要的： （ 4 ）由于dopp1oy展宽的存在，当探测场与驱动场的传播方向相反时，增益在探测场失谐的某一段区域产生振荡，且振荡的振幅、频率失谐范围的大小与dopper展宽的取值有关。
• From the past research work , it has been known that the main mechanisms of spectral lines broadening in the atmospheres of stars are doppler broadening , spectral lines broadening by rotation and expending , pressure broadening ( stark broadening ) , natural broadening , spectral lines broadening in magnetic field , sonic waves and alfv e n waves broadening , etc . but it is not enough to explain the recent observation phenomena by above theories of spectral lines broadening
  以往的研究已经判明，在恒星大气内谱线致宽的主要机制是多普勒致宽、自转源或膨胀源引起的致宽、压力致宽(斯塔克致宽) 、自然致宽、磁场引起的加宽、声波及阿尔文波致宽等。然而，已有的谱线致宽理论不足以解释最近的一些观测现象，仍存在观测值与理论值之间的差异。
