Light scattering from a magnetically tunable dense random medium with weak dissipation : ferrofluid
M. Shalini, Avinash A. Deshpande, Divya Sharma +3
We present a semi-phenomenological treatment of light transmission through and its reflection from a ferrofluid, which we regard as a magnetically tunable system of dense random di…
Molecular symmetry effects in the ionization of CS by intense, few-cycle laser pulses
Deepak Mathur, Aditya K. Dharmadhikari, Firoz A. Rajgara +1
Few-cycle pulses of intense 800 nm light are used to probe ionization and dissociation of carbon disulfide in the intensity and temporal regime where rescattering is expected to do…
Control of the Onset of Filamentation in Condensed Media
A. K. Dharmadhikari, K. Alti, J. A. Dharmadhikari +1
Propagation of intense, ultrashort laser pulses through condensed media like crystals of BaF and sapphire results in the formation of filaments. We demonstrate that the onset o…
Multiple optical traps from a single laser beam using a mechanical element
J. A. Dharmadhikari, A. K. Dharmadhikari, D. Mathur
The use of a wire mesh facilitates creation of multiple optical traps for manipulation of small micron or sub-micron particles. Such an array of optical traps can be easily control…
All-optical switching with bacteriorhodopsin
S. Roy, P. Sharma, A. K. Dharmadhikari +1
All-optical, mirrorless switching and bistability is demonstrated with bacteriorhodopsin (bR). A low-power, 532 nm laser beam modulates the transmission of a cw laser beam at 635 n…
