Development and characterization of novel active and passive wide-band semiconductor materials and light sources based on transition metal (TM²⁺, e.g., Cr²⁺ or Fe²⁺) doped binary and ternary chalcogenide crystals for laser sensing and spectroscopic applications.

Development of sensors based on lasers spectroscopy and microscopy methods such as; Atomic Force Microscopy , Near-field Microscopy, Infrared Absorption Spectroscopy, Fluorescence and Raman spectroscopes, Surface Enhanced Raman Spectroscopy, Tip Enhanced Raman Spectroscopy, Laser Induced Breakdown Spectroscopy and Photoacoustic Spectroscopy for detection of volatile organic compounds, explosives, chemical and biological toxins for counter-terrorism, environmental monitoring and biomedical applications.

The work in progress includes:

• Development heavy metal detection LIBS/LEAFS platform based on Cr:ZnSe/S for an ultrasensitive (sub-ppb level) and fast detection of Cd, Mn and As with sensitivity comparable to gold standards techniques such as Mass Spectrometry and Atomic Absorption Spectrophotometry.
• Development of ultracompact spectral comb source with instantaneous bandwidth of 310 µm for detection of multiple trace organic molecules using infrared Dual Comb Spectroscopy.
• Development of high power pulsed Fe:ZnSe lasers tunable in 3.8-4.9 μm spectral range for direct optical pumping of CO2 Laser.
