Abstract:
Two-photon absorption coefficients in ultraviolet-grade optical fibers are measured in the range of 219-260 nm. A frequency-doubled tunable dye laser is used as the light source. The two-photon absorption coefficient increases exponentially with an increase in the photon energy. The exciton peak does not appear in the spectrum. Theoretical values are calculated by the Keldysh formula and compared with the experimental results.

01:16Spectrophotometry: Introduction
Spectrophotometry is the quantitative measurement of the absorption, reflection, diffraction, or transmission of electromagnetic radiation through a material as a function of the intensity and wavelength of the radiation. A spectrophotometer is a device used to measure the change in the radiation intensity caused by its interaction with the material.
The essential components of a spectrophotometer include a source of electromagnetic radiation, a slot for placing a material to be analyzed, and a...

01:07Propagation of Waves
When a wave propagates from one medium to another, part of it may get reflected in the first medium, and part of it may get transmitted to the second medium. In such a case, the interface of the two mediums can be considered as a boundary that is neither fixed nor free.
Consider a scenario where a wave propagates from a string of low linear mass density to a string of high linear mass density. In such a case, the reflected wave is out of phase with respect to the incident wave, however the...
