此外，这一蓝失谐的聚焦中空光束还可以用于中性原子的激光冷却与囚禁，甚至用于研究冷原子在聚焦中空光束中的绝热压缩(加热)和绝热膨胀(冷却)过程。 - By numerical calculation of the solution , in chapter 3 , we give nonlinear theory of the open v - type system with a monochromatic incoherent pump . the chapter comprises sections of resonant nonlinear theory and off - resonant nonlinear theory
利用解析解的数值计算，第三章讨论了单色非相干泵浦系统的非线性理论，包括共振的非线性理论和失谐的非线性理论两节。 - We study the time evolution law of the atomic response in an open - type inversionless lasing system when the probe or driving field is off - resonance , and compare the law with that obtained when the probe and driving fields are resonant . we find that the detuning has considerable effects on the time evolution law : when the probe or driving fields is off - resonance , the dispersive responses for the probe and driving fields are no longer 0 and the two - photon coherence is no longer a pure real ; the variation of the probe detuning can make the time evolution law of the population distributions and the gain ( absorbtion ) of the driving field changing obviously ; with detuning increasing , the time evolution behavior of the gain ( absorbtion ) , dispersion of the probe field and the two - photon coherence will gradually diviate from the evolution law of the standard damped oscillator ; with the driving detuning increasing , the oscillating time of the dispersion of the driving field becomes longer , the amplitude and the stationary value increase
研究了探测场或驱动场失谐情况下开放的型无粒子数反转激光系统中原子响应的时间演化规律,并与探测场和驱动场都共振时的演化规律进行了比较.我们发现失谐对时间演化规律有显著的影响;当驱动场或探测场失谐时,原子对探测场和驱动场色散的响应不再为零,双光子相干不再是纯实量;探测场失谐的变化将使粒子布居和驱动场增益(吸收)的时间演化规律明显改变;随着失谐的增大,探测场增益(吸收) 、色散和双光子相干随时间的演化行为逐渐偏离标准阻尼振子的演化规律;驱动场色散驱动场失谐量的增加而振荡时间变长,振幅和稳定值变大 - 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。
