Random lasers use disordered structures to produce light, which is usually emitted in many directions. A random laser that can produce a collimated beam offers a wide range of applications, from ...

What prompted the MIT team to research and develop a nanoscale "flashlight"? Details on the metasurface that was designed to create the source-beam collimator. How a DNN, CNN, and machine learning ...

A research team at Los Alamos National Laboratory has developed an inexpensive method for generating a high-power, low-frequency, collimated sound beam. In addition to penetrating deeply, this beam ...

Laser lenses are the optical lenses that are used in laser-based devices for a variety of laser applications such as but not limited to laser illumination, laser collimator, laser scanning, laser ...
