Lasing without inversion and enhancement of the index of refraction via interference of incoherent pump processes Academic Article uri icon


  • For the quantum beat laser we investigate the generation of coherence between the two lower levels via incoherent pumping of these two levels to a fourth auxiliary level. It will be shown that this way of establishing coherence also leads to lasing without inversion and to an enhancement of the index of refraction at a point of vanishing absorption. 1992.
