Description
Summary:O432.1+2; It is shown that in an open lambda type atomic system,the gain and dispersion of the probe field are quit sensitive to variation of spontaneously generally coherence (SGC).The value of the parameter p reflects whether SGC effect exists and the size of SGC effect.Under certain condition,when p=0.002,electromagnetically induced transparency occurs; when p≠0.002,lasing without inversion can be realized;when p=0.95,high index of the refraction with zero absorption can be obtained.
