Quadrature Squeezing with Normally Ordered Noise Operators
Merid Tufa, Fesseha Kassahun
We have considered the interaction of subharmonic light modes with a three-level atom in a closed cavity coupled to a vacuum reservoir. We carry out analysis by normally ordering t…
Squeezing in Both the Plus and Minus Quadratures with the Uncertainty Relation Perfectly Holding
Ayana Yihunie, Fesseha Kassahun
We have considered a cavity mode driven by coherent light and interacting with a three-level atom available in an open cavity coupled to a vacuum reservoir. We have carried out our…
Quadrature Squeezing in the Cavity Mode Driven by Coherent Light and Interacting with Two-Level Atom
Beyene Bashu, Fesseha Kassahun
We have analyzed the quadrature squeezing in a cavity mode driven by coherent light and interacting with a two-level atom. We have found that the cavity mode is in a squeezed state…
A degenerate three-level laser coupled to a squeezed vacuum reservoir
Dawit Hiluf, Fesseha Kassahun
Employing the master equation for a three-level laser driven by coherent light and coupled to a squeezed vacuum reservoir, we obtain stochastic differential equations associated wi…
The Commutation Relation for Cavity Mode Operators
Fesseha Kassahun
We have obtained the commutation relation for a cavity mode driven by coherent light and interacting with a two-level atom. We have found that the commutation relation for a free c…
Quantum Analysis of Subharmonic Generation Via First-Order Hamiltonian
Fesseha Kassahun
We have established that the mean photon number obtained employing the conventional Hamiltonian for the twin light beams with the same frequency, produced by a subharmonic generato…
Two-Level Laser Dynamics with a Noiseless Vacuum Reservoir
Fesseha Kassahun
We analyze the quantum properties of the light generated by a two-level laser in which the two-level atoms available in a closed cavity are pumped to the upper level by means of el…
Superposed Coherent and Squeezed Light
Fesseha Kassahun
We first calculate the mean photon number and quadrature variance of superposed coherent and squeezed light, following a procedure of analysis based on combining the Hamiltonians a…
Three-Level Laser Dynamics with the Atoms Pumped by Electron Bombardment
Fesseha Kassahun
We analyze the quantum properties of the light generated by a three-level laser with a closed cavity and coupled to a vacuum reservoir. The three-level atoms available in the cavit…
