Gain without inversion in a V-type system with low coherence decay rate for the upper levels

2026-07-072026-07-07http://salesiana.dossiersoluciones.com/handle/123456789/86146Inversionless gain is observed in a V-type inhomogeneously broadened system without introducing any incoherent pumping and only by changing the collisional dephasing decay rate. In this system sub-Doppler linewidth is achieved with off-resonance pump detuning.9 pages, 4 figuresAtomic PhysicsGain without inversion in a V-type system with low coherence decay rate for the upper levelstext
