Super-resolution Fluorescence Microscopy01:37

Super-resolution Fluorescence Microscopy

Super-resolution fluorescence microscopy (SRFM) provides a better resolution than conventional fluorescence microscopy by reducing the point spread function (PSF). PSF is the light intensity distribution from a point that causes it to appear blurred. Due to PSF, each fluorescing point appears bigger than its actual size, and it is the PSF interference of nearby fluorophores that causes the blurred image. Various approaches to achieving higher resolution through SRFM have recently been developed.

Deactivation Processes: Jablonski Diagram

Luminescence, the emission of light by a substance that has absorbed energy, is a process that involves the interaction of molecules with light. The energy-level diagram, or Jablonski diagram, is a graphical representation of these interactions, illustrating the various states and transitions a molecule can undergo. In a typical Jablonski diagram, the lowest horizontal line represents the ground-state energy of the molecule, which is usually a singlet state. This state represents the energies...
Confocal Fluorescence Microscopy01:16

Confocal Fluorescence Microscopy

Confocal microscopy is an advanced microscopic technique. The prime advantage of the confocal microscope over other microscopy techniques is its ability to block the out-of-focus light from the illuminated samples using pinholes. It is widely used with fluorescence optics to obtain high-resolution, sharp contrast images. Unlike optical microscopes, confocal microscopes use a focused beam of light laser to scan the entire sample surface at different z-planes. These microscopes are, therefore,...

Area of Science:

  • Atomic physics
  • Quantum optics
  • Many-body physics

Background:

  • Superradiance describes cooperative spontaneous emission from identical atoms.
  • This phenomenon offers insights into photon-atom many-body physics.

  • To establish a simple spectroscopic method for analyzing superradiant emission.

Main Methods:

  • Embedding resonant atoms within a planar cavity.
  • Utilizing synchrotron radiation for collective excitation.
  • Simultaneously measuring temporal evolution of superradiant decay and collective Lamb shift.

Main Results:

  • Achieved collective excitation into a purely superradiant state.
  • Observed a substantial radiative shift in transition energy (collective Lamb shift).
  • Successfully measured temporal dynamics of superradiant decay and collective Lamb shift for 57Fe nuclei.

Conclusions:

  • Demonstrated a method for achieving and studying superradiance in a cavity-based system.
  • Validated the existence and measurement of the collective Lamb shift.
  • Provided a straightforward spectroscopic technique for analyzing superradiant emission.
