Laser spectroscopy

Laser-induced plasma has been used for different diagnostic and technological applications as detection, thin film deposition, and elemental identification.

Photodissociation, photolysis, or photodecomposition is a chemical reaction in which a chemical compound is broken down by photons.

Sum frequency generation vibrational spectroscopy (SFG-VS) is used to characterize vibrational bonds of molecules at surfaces or interfaces.

SHG measurements provide information about: surface coverage, molecular orientation, adsorbtion-desorbtion processes, and reactions at interfaces.

The advantage of pump-probe spectroscopy is direct investigation of dynamics – excitation relaxation, energy transfer, photochemical reactions dynamics and movement of particles, structural changes.

Time-resolved Photoluminescence Spectroscopy (TRPL) is a contactless method to characterize recombination and transport in solid materials.

Gas-phase ion luminescence spectroscopy is used to determine intrinsic electronic transition energies in the absence of a disturbing environment.

Supercontinuum “White Light Lasers” have become a well-established turn-key fiber-laser technology addressing a wide range of applications from biomedical imaging to optical device characterization.

Time-resolved photoconductivity (TRMC) are key techniques used to perform the contactless determination of carrier density, transport, trapping, and recombination parameters in charge transport materials.

In nonlinear optics, z-scan technique is used to measure the non-linear index n₂ (Kerr nonlinearity) and the non-linear absorption coefficient Δα.

LIDAR sends out short laser pulses into the atmosphere, where all along its path, the light is scattered by small particles, aerosols, and molecules of the air and is collected by telescope for analysis.

Laser-induced breakdown spectroscopy (LIBS) utilizes a high intensity short laser pulse to convert a very small amount of target material to plasma for optical analysis of the spectra

Terahertz time-domain spectroscopy (THz-TDS) probes inter-molecular interactions within solid materials. THz-TDS covers the spectral region of 0.1-10 THz which is a low energy and non-ionizing region of the electromagnetic spectrum.
