Optical physics


Optical physics is the study of the fundamental properties of light and its interaction with matter. This includes classical optical phenomena such as reflection, refraction, diffraction and interference, and also studying the quantum mechanical properties of individual packets of lights known as photons.

    Diffraction-free light-sheet beams, strongly confined in one axis, are typically thought to self-bend during propagation in free space and cannot be made flat. Now, diffraction-free planar light sheets in air have been realized by exploiting polychromatic pulsed beams.

    Simultaneous trapping, alignment and anti-Stokes fluorescence cooling of Yb3+:YLF nanocrystals from room temperature to temperatures as low as about 130 K can now be realized using a single-beam optical dipole trap within a low-pressure environment.
