Threshold non-linear absorption in Zeeman transitions
Andal Narayan, Abheera Hazra, S. N. Sandhya
We experimentally study the absorption spectroscopy from a collection of gaseous atoms at room temperature irradiated with three fields. Two of these fields are in a pump…

Resonance flourescence in atomic coherent systems: spectral features
S N Sandhya
We study resonance flourescence in a four level ladder system and illustrate some novel features due to quantum interference and atomic coherence effects. We find that under three…
