A tunable Doppler-free dichroic lock for laser frequency stabilization
Vivek Singh, V. B. Tiwari, S. R. Mishra +1
We propose and demonstrate a laser frequency stabilization scheme which generates a dispersion-like tunable Doppler-free dichroic lock (TDFDL) signal. This signal offers a wide tun…
Electromagnetically induced absorption in metastable 83Kr atoms
Y. B. Kale, V. B. Tiwari, S. R. Mishra +2
We report electromagnetically induced absorption (EIA) resonances of sub-natural linewidth (FWHM) in metastable noble gas 83Kr* atoms using degenerate two level schemes (DTLSs). Th…
Resolution of hyperfine transitions in metastable 83Kr using Electromagnetically Induced Transparency
Y. B. Kale, S. R. Mishra, V. B. Tiwari +2
Narrow linewidth signals of Electromagnetically Induced Transparency (EIT) in the metastable 83Kr have been observed for the first time. Various hyperfine transitions in 4p55s[3/2]…
Velocity selective bi-polarization spectroscopy for laser cooling of metastable Krypton atoms
Y. B. Kale, V. B. Tiwari, S. Singh +2
We report a velocity selective bi-polarization spectroscopy (VS-BPS) technique to generate a background-free, dispersion-like reference signal which is tunable over a wide range of…
Electromagnetically induced transparency in cold 85Rb atoms trapped in the ground hyperfine F = 2 state
V. B. Tiwari, S. Singh, H. S. Rawat +2
We report electromagnetically induced transparency (EIT) in cold 85Rb atoms, trapped in the lower hyperfine level F = 2, of the ground state 5 (Tiwari V B \textit{et a…
Optical Limiting in Single-walled Carbon Nanotube Suspensions
S. R. Mishra, H. S. Rawat, S. C. Mehendale +5
Optical limiting behaviour of suspensions of single-walled carbon nanotubes in water, ethanol and ethylene glycol is reported. Experiments with 532 nm, 15 nsec duration laser pulse…
