... The Letter by Deng et al. [1] presents an analytic theoretical description of matter-wave superradiance [2] which claims to go beyond previous theoretical frameworks. I show here that the theory presented in this Letter is not a description of superradiance per se, but rather an elegant perturbative ...

The width of the Sinc function (or diffraction pattern in general) is inversely proportional to the width of the aperture. For example if the rec ...

Sum frequency generation spectroscopy (SFG)
... SFG has advantages in its ability to be monolayer surface sensitive, ability to be performed in situ (for example aqueous surfaces and in gases), and not causing much damage to the sample surface. SFG is comparable to second harmonic generation (SFG is a more general form) and Infrared and Raman ...

Laser beam profiler
A laser beam profiler captures, displays, and records the spatial intensity profile of a laser beam at a particular plane transverse to the beam propagation path. Since there are many types of lasers — ultraviolet, visible, infrared, continuous wave, pulsed, high-power, low-power — there is an assortment of instrumentation for measuring laser beam profiles. No single laser beam profiler can handle every power level, pulse duration, repetition rate, wavelength, and beam size.
