Lasers, Photonics and Quantum Optics


Groups Detail

Introduction

Currently, research effort is focused on three projects.

  • Collisions in Laser Created Sparks in Gas Mixtures.
  • Synthesis of Nanoparticles through Laser Ablation in Gas Phase as well as Liquid Environment.
  • Preparation of Thin Films through Pulsed Laser Deposition

A Q-Switched Nd:YaG Laser with output at 1064nm, 53nm2 and 355nm is the main source for this work. A UV- Visible Spectrometer covering 300-900 nm range is available for on-line spectroscopic measurements.

Photonics

The science of photonics includes the generation, emission, transmission, modulation, signal processing, switching, amplification, and detection/sensing of light. The term photonics thereby emphasizes that photons are neither particles nor waves ? they are different in that they have both particle and wave nature. It covers all technical applications of light over the whole spectrum from ultraviolet over the visible to the near-, mid- and far-infrared. Most applications, however, are in the range of the visible and near infrared light. The term photonics developed as an outgrowth of the first practical semiconductor light emitters invented in the early 1960s and optical fibers developed in the 1970s. This group is establishing a state of the art ultrafast optics laboratory. In this regard a laser of femto second is commissioned in the laboratory of ultrafast optics which will install soon.

Quantum Optics

Currently the group is working in the field of theoretical quantum optics and his main area of research includes; sub-wavelength atom localization, quantum state measurement of the radiation field, spontaneous emission spectrum, coherent control of the GH-shift, propagation effects experienced by light pulses in atomic media, electromagnetically induced transparency, slow fast and backward propagating light, non-adiabatic optical transitions, wave shaping, control of optical response, decay rate of exited atoms in dielectric media, engineering entanglements in cavity QED systems, entanglement dynamics, quantum teleportation and quantum entanglement.
