Abstract
The Photonnusber eigenstate (PNE state) generated in a oneatos sphoton sicrolaser systes via the atosic seasuresent for the outofresonance case is shown. The effect of detuning on the probability of obtaining state after having k atoss passed the cavity is discussed. THEORY A beau of lowdensity twolevel atoss is injected into ahighQ cavity at such a low rate that at lost one atos at a t lie is present inside the cay i ty. The cavi ty loss is negi igible. Consider a twolevel atos interacting with a singlesode field via the iphoton transition for the near ly resonant case. The effect i ye Has i lton ian for th is systes in the RWA is Hf cact + q/2)+i1 A q/2+t1g( a'' cy. . Q" ( 1) where L(. )i() is the detuning and ''fi is the energy difference between the two levels of atos g is the iphoton transition atosfield coupling constant Q and *'' are the annihilation and creation operators of the field and ca is the frequency of field a3 and a. are the Pauli spin operators. Assuse that the field is in PNE state at a tue t1 in which the ith excited atol is just going to be injected. r is the tile for the ith atoi to pass through the cavity. The density operator p (t+t ) is p (t+t )U( i: ) p
