As. Zibrov et al., EXPERIMENTAL DEMONSTRATION OF CONTINUOUS-WAVE AMPLIFICATION WITHOUT INVERSION VIA QUANTUM INTERFERENCE IN RB, Laser physics, 5(3), 1995, pp. 553-555
Continuous wave amplification without inversion is demonstrated experi
mentally in a V-type configuration within D-1 and D-2 lines of Rb vapo
r. It is shown that the effect is due to the atomic interference. The
experimental results are in good agreement with theoretical prediction
