One of America's most recognized and experienced broadcast journalists, Lesley Stahl has been a "60 Minutes" correspondent since 1991. Amid attacks from cheaply made Iranian Shahed drones, the U.S. is ...

Six years after their birth, terahertz quantum-cascade lasers can now deliver milliwatts or more of continuous-wave coherent radiation throughout the terahertz range — the spectral regime between ...

As Iran and Russia deploy thousands of inexpensive kamikaze drones, the U.S. defense industry is seeking a cost-effective solution. AeroVironment (AV) introduced the LOCUST X3, the third generation of ...

Abstract: Using numerical modeling and experimental measurements, we quantify the amount of phase noise randomness produced by a gain-switched laser diode. This has applications in QKD and QRNG where ...
