  3. 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

    發現： （ 1 ）在考慮doppler展寬的情況下，通過選取合適的實驗室條件（比如合適的原子環境溫度等）可得到合適doppler展寬值，從而使系統獲得最佳增益； （ 2 ）要想實現系統的頻率上轉換，同時又要獲得足夠強的無反轉激光增益，則系統頻率轉換比不能選取的太大； （ 3 ）對于開放系統，比較小的粒子注入速率比與退出速率對產生無反轉激光是有利碩士學位論文摘要的： （ 4 ）由於dopp1oy展寬的存在，當探測場與驅動場的傳播方向相反時，增益在探測場失諧的某一段區域產生振蕩，且振蕩的振幅、頻率失諧范圍的大小與dopper展寬的取值有關。
