Fluorescence, Phosphorescence, and Photoluminescence Spectroscopy
Fluorescence, phosphorescence and photoluminescence occur when a sample is excited by absorbing photons and then emits them with a decay time that is characteristic of the sample environment.

Astronomical Imaging
Astronomical imaging can be broadly divided into two categories: (1) steady-state imaging, in which long exposures are required to capture ultra-low-light-level objects, and (2) time-resolved photometry, in which integration times range from milliseconds to a few seconds.

General Raman
The most common application of Raman spectroscopy involves the vibrational energy levels of a molecule. Incident laser light in the UV, visible or NIR, is scattered from molecular vibrational modes.

Fusion Research


Bose-Einstein Condensate
Bose-Einstein condensate (BEC) can be regarded as matter made from matter waves. It is formed when a gas composed of a certain kind of particles, referred to as “bosonic” particles, is cooled very close to absolute zero.

Coherent Anti-Stokes Raman Spectroscopy
Coherent Anti-Stokes Raman spectroscopy (CARS) a type of non-linear Raman spectroscopy. Instead of the traditional single laser, two very strong collinear lasers irradiate a sample.

Combustion researchers rely on laser-based optical diagnostic techniques as essential tools in understanding and improving the combustion process.

Nanotechnology helps scientists and engineers create faster electronics as well as ultrastrong and extremely light structural materials.

Resonance Raman Spectroscopy
Instead of fluorescence, some types of colored molecules produce strong Raman scattering at certain conditions. This effect was called Resonance Raman.

Microscopic Study of Dopant Distribution in Europium Doped SrGa2S4: Impact on Thermal Quenching and Phosphor Performance
Cathodoluminescence in an electron microscope detected by sensitive spectgroscopy helps to optimize luminescent materials for example for applications in happens when electrons that are hitting a material cause the emission/luminescence of photons. Here the emission is initiated with a scanning electron beam in an electron microscope. The background for this research is to optimize phosphors for LED devices that are necessary to obtain emission of white light for example. Electron microscopy and sensitive spectroscopy helps to get deeper insights and to optimize new luminescent materials for devices.
