• Finally we focus our attention on studying the emission spectrum of two atoms driven by a single - mode field in an ideal cavity . we showed that the atomic emission spectrum is insensitive to the phase of field for the two atoms initially in the coherent superposition state tf / = v2 / 2 ( j + , - ) h ? + } ) , when the two atoms is initially prepared in ( fs * } = cos ( 0 / 2 ] + , + ) + sm ( 0 / 2 ) ei ' p - , - ) , the atomic emission spectrum is associated with not only the field photon - number distribution and the atomic populations , but also the phases of the field and the atomic dipole
  接着考察了好腔中由单模量子场驱动的双原子发射谱，结果表明初态为的双原子发射谱与驱动场的相位无关；而初态为的双原子发射谱不仅与光场的光子数分布以及原子的布居数有关，而且依赖于光场的相位以及原子偶极矩的相位，并且在适当的条件下，压缩真空场可将双原子俘获在相干叠加态。
• The analytical solutions of the gain , dispersion and population difference in the steady state of an open ladder lasing without inversion ( lwi ) system are at first given when the phase fluctuation of the driving field is considered . then the effects of the driving field phase fluctuation on the gain , dispersion and population difference are analyzed by the numerical results from the analytical solutions . our research shows that the phase fluctuation of the driving field will results in a finite line width ; with the line width increasing , the gain decreases monotonously , however , variation of the dispersion isn ? t monotonous , it has a maximum value when the line width takes some value ; the line width varying can ? t lead to change lasing from without to with population inversion
