Simultaneous High-resolution Electron and Laser Beam Irradiation for Luminescence Studies in a Scanning Electron
SUMMARY Many scientific studies utilize scanning electron microscopy (SEM), cathodoluminiescence (CL), photoluminescence (PL), and Raman Spectroscopy techniques to characterize newfound materials. This Lehigh University technology combines all of these techniques into one instrument by aligning an electron and laser beam within a high-resolution c...

Compact and Portable Terahertz Source by Mixing Two Frequencies Generated Simultaneously by Single Solid-State Laser
SUMMARY Lehigh University has developed a compact, portable terahertz (THz) source that uses difference frequency generation (DFG) in a Gallium Selenide (GaSe) crystal by mixing dual frequencies from a single solid-state laser. Experimental results of this technology show the average THz output power can be as high as 1 μW at 1.64 THz (182 &...
