Inversionless amplification in a three-level medium. Academic Article uri icon


  • We study all possible resonant three-level configurations where a low-frequency coherent pump can be converted into a high-frequency field in the absence of population inversion at both atomic high-frequency transitions. We identify two different mechanisms that provide such inversionless amplification. 1992 The American Physical Society.
