Researchers at Lehigh's Center for Photonics and Nanoelectronics are using a new phase-locking technique to achieve record-high output power for terahertz lasers and reported the highest radiative efficiency for any single-wavelength semiconductor quantum cascade laser (QCL).
The ‘Bug Zapper’ uses UV-C light to damage the DNA of pathogens, including the coronavirus, to enable the sterilization and reuse of N95 masks when new ones are unavailable.
