JAP04 - Anglictina pro fyziky 4 Refractive index
... How can we measure the refractive index of air? A value of the refractive index is now being achieved generally by two methods: the first of them (indirect) is based on modified Edlen’s formula where atmospheric conditions as local pressure, temperature, humidity, and CO2 concentration are measured ...

... The optical tweezer is used to trap the micro dielectric particle, which is embedded in a medium as gas, fluid [1, 2, 3]. Usually, the tweezers in many experiments are conducted using the CW laser. It is well known that the CW laser with the power of a few milliwatt can only produce the radiation fo ...

Writing Words on Atoms
... Usually scientists look at an atom in its “ground state”, where all electrons occupy the lowest energy levels – because of attractive forces between nuclei and electrons these are the ones closest to the nuclei. Electromagnetic waves (e.g. laser light) can transfer electrons to “excited states” with ...

7.1.3 Optimizing Light Confinement and Gain in Laser Diodes
... Light is reflected, diffracted, and absorbed according to the (complex) refractive index nr of the medium. This is foremost a function of the material itself, but also of the densities of available electrons. In regions with a high gain coefficient we have a high density of electrons, too, and thus ...
