Photophoretic Trapping: Fundamentals, Advances and Future Directions
Anita Pahi, Kirty Ranjan Sahoo, Souvik Sil +1
Photophoretic forces, several orders of magnitude stronger than radiation pressure, enable particle trapping at remarkably low optical intensities and have opened pathways to appli…
Simultaneous active and diffusive behaviour of asymmetric microclusters in a photophoretic trap
Anita Pahi, Kirty Ranjan Sahoo, Biswajit Das +2
Active and diffusive motion in Brownian particles are regularly observed in fluidic environments, albeit at different time scales. Here, we experimentally study the dynamics of hig…
A study of the coupled dynamics of asymmetric absorbing clusters in a photophoretic trap
Anita Pahi, Shuvojit paul, Ayan Banerjee
We report a study on the dynamics of absorbing asymmetric carbon clusters trapped by a loosely focused Gaussian beam using photophoretic force. At high laser powers, all the trappe…
An ultra-stable three-dimensional photophoretic trap in air facilitated by a single multimode fiber
Souvik Sil, Anita Pahi, Aman Anil Punse +1
Photophoretic forces - which are of thermal origin - have defined an alternative route of optical trapping of absorbing microparticles in air. Here, we show that a single multi-mod…
Trapping multiple absorbing particles in air using an optical fiber by photophoretic forces
Souvik Sil, Anita Pahi, Aman Anil Punse +1
We demonstrate photophoretic force-based optical trapping of multiple absorbing particles in air by loosely focusing a Gaussian beam with a series of convex lenses of different foc…
