New technique to study superheavy elements

Jul 13, 2020So far, optical spectroscopy ends at nobelium, element 102 in the periodic table. Current techniques are at the limit of what is feasible, explained Laatiaoui. From the next heavier element on, the physicochemical properties change abruptly and impede providing samples in suitable atomic states. Get price

The role of stress in the time

Aug 05, 2009Amorphous silicon inverse opals with a complete photonic band gap have been studied with optical pump-probe spectroscopy. The pump-generated free carriers cause the reflection near the band gap to be lowered for the first few picoseconds due to induced absorption. After ∼ 5 ps, this effect disappears and an unexpected blue spectral shift is seen in the photonic band gap. Get price

US Patent # 5,225,778. Optical pumping, resonance

Optical pumping, resonance magnetometer using a sequential polarization Abstract. An improved optical pumping magnetometer with sequential polarization for measurement of weak magnetic fields involves a device which sequentially modifies the polarization either in the direction of the polarization or from clockwise to counterclockwise circular polarization.

Optical Coating Services Selection Guide

Optical coating services design optical coatings and apply them to crystal, fiber, glass, metal, or polymer substrates to produce optical components. These coatings reduce reflection both internally and externally, increasing the amount of light that reaches the eye and improving brightness and contrast. Get price

REU 2002

Both optical pumping and applied magnetic field are used to induce spin polarization and both photoluminescence and electroluminescence (respectively) are used to detect the injected electron spin-polarization in the semiconductor. In research done last year at the University of Minnesota, one of the authors (STR) measured the magnetic Get price

Spin Noise Spectroscopy in Rb Vapor

The experiment is essentially a noise-based analog to the popular optical pumping experiment already present in many undergraduate laboratories. In this case, Faraday rotation is used to probe spin fluctuations of a gas of alkali atoms in thermal equilibrium in a small magnetic field.
