Advances in inorganic nanoparticles trapping stiffness measurement: A promising tool for energy and environmental study

Energy Reviews, 2023
Optical tweezers system has emerged as an efficient tool to manipulate tiny particles in a non-invasive way. Trapping stiffness, as an essential parameter of an optical potential well, represents the trapping stability.

Force measurements with optical tweezers inside living cells [PDF]

, 2014
The force exerted by optical tweezers can be measured by tracking the momentum changes of the trapping beam, a method which is more general and powerful than traditional calibration techniques as it is based on first principles, but which has not been ...

Optical trapping with superfocused high-M2 laser diode beam [PDF]

, 2015
Many applications of high-power laser diodes demand tight focusing. This is often not possible due to the multimode nature of semiconductor laser radiation possessing beam propagation parameter M2 values in double-digits.

Optically programmable excitonic traps [PDF]

Scientific Reports, 2013
With atomic systems, optically programmed trapping potentials have led to remarkable progress in quantum optics and quantum information science. Programmable trapping potentials could have a similar impact on studies of semiconductor quasi-particles, particularly excitons.
