Accounting for the mistake in our earlier analysis [Phys. Rev. A 46, R3613 (1992)] that was pointed out by Zhu and Xiao [recent Comment, Phys. Rev. A 49, 2203 (1994)] we show that lasing without inversion is still achieved in our more general model description of a ssV-shaped system.

Comment on ‘‘Theory of lasers without inversion’’

Shi-Yao Zhu, James D. Cresser, H. Fearn

We prove that lasing without inversion is impossible in the three-level system with two active upper levels that are mixed by applied low-frequency electromagnetic radiation. Such lasing was recently proposed by Blok and Krochik [Phys. Rev. A 41, 1517 (1990)].
