Using a set of Zeeman sublevels of an alkali atom such as rubidium or sodium, we propose to construct a pair of coherentc population trap (CPT) states, which can be individually addressed and populated at will. The system can be arranged such that th

The atomic interferometry by Kasevich and Chu (Phys. Rev. Lett. 67, 181(1991)) has been the beginning of a range of very sensitive measurement techniques. We present a complete density matrix analysis of this technique. Although there has been severa

External optical feedback in vertical-cavity surface-emitting laser (VCSEL) is found to influence its output intensity. We studied the effect of the amount of total output polarisation feedback and polarisation-selective feedback on the output intens

We have simulated atmospheric effects such as fog and smoke in laboratory environment to simulate depolarization due to atmospheric effects during a free space optical communication. This has been used to study noise in two components of Quaternary e

The swimming of a bacterium in fluids occurs in a low Reynolds number regime. The ability to confine the swimming motion by trapping a bacterium in laser light, can give information on the propulsion coefficients, which are important in explaining th

A robust system for use of Quantum Computation using neutral atoms is presented in this communication. This scheme exploits a multilevel atomic system interacting with two lasers in such a way that it leads to formation of two Coherent Population Tra

We have built a set up to achieve a collimated atomic Lithium beam to be used for plasma edge diagnostics. The collimation is achieved by two-dimensional laser cooling, and such a beam could be very useful to obtain electron density at the edge of a
