Abstract Efficient spectral narrowing and accurately reproducible tuning of a dye laser has been achieved by the combination of a low-loss narrow-band interference filter and a solid-quartz-plate-Fabry-Perot-etalon. Bandwidths as small as 5-10-3 Å were obtained by this simple system increasing the spectral density by a factor of at least 2 · 103.

Atom Interaction

We have investigated the interaction of two level atom with time varying quadrature squeezed light field. Jaynes-Cummings model is used for solving the atom radiation interaction. Time evolution of the system for different squeezing parameter and phase have been studied. There are no well-defined revivals in population inversion when the squeezed phase is π and the squeezing parameter is greater than 0.5. Using a time varying frequency for the light field, it is found that the randomness of the population inversion and the collapse revival phenomena can be controlled. Frequency modulation of the field can thus be used as a tool for manipulating the squeezed light atom interaction.

Laser Model

The dynamics of the laser model based on the nonlinear coupling of light-field with boson elementary excitation is improved. A rate equation of pumping system directly coupled with the boson matter is added to the original equations. The system as a whole, therefore, becomes a perfect self-organized one, but the character of mirrorless unchanges, which is a character essentially different from conventional lasers, and the laser threshold behavior of second-order-like transition also remains. There is some resemblance between the new revised laser model and Maxwell–Bloch two-level-atom laser model.
