Durability improvement of concrete in the complex environments of chloride, sulfate and freeze-thaw, by incorporating compound mineral additives of fly ash, slag, diatomite and zeolite in concrete, was studied through the approach of orthogonal array

An analytical expression of emission spectrum for Λ -type three-level atom interacted with two-mode cavity field is given. The characters of the emission spectrum for the field in photon number state, coherent state and SU(2) coherent state are exhi

We show that quantum interference from spontaneous decay in a three-level -type system can be realized in the dressed-state picture of coherently driven systems. The physical realization relaxes the stringent conditions upon the level spacing and qua

Dynamically induced irreversibility is found to take place in coherently driven Λ systems in which there is no conventional source of irreversible population pumping. When the rates of spontaneous emission from the excited state to two metastable st

In this paper we investigate the quantum statistical properties in a cascade laser system with the lower transition being in a quantum-beat configuration. It is shown that a type of three-mode squeezing may be generated. The fluctuations of the inten

For a four-level double-V laser without inversion we show that the interference of spontaneous decays leads to intensity noise squeezing. The optimum amount of noise reduction is 50%, which is the maximum squeezing in a resonant three-level inversion

Using the `dressed-atom-dressed-mode' approach and separating the decoupled atomic state, we investigate the statistical properties of a quantum-beat laser without inversion. While the fluctuations of the relative amplitude and phase are retained at

A cascade system can produce lasers with and without inversion simultaneously. Lasing without inversion is maintained by two-photon coherence. Here we examine the quantum statistical properties of cascade lasers from a four level atomic system with t
