An outdoor laser light show/demonstration is considered to be a laser product by the Food and Drug Administration’s Center for Devices and Radiological Health (CDRH) and, if the irradiance is greater than 5 miliwatts per square centimeter, the demonstration requires a variance to Title 21, Code of Federal Regulations, Section 1040.11c. The variance (issued by the CDRH) requires the laser user to notify the Federal Aviation Administration (FAA) of the proposed laser operation and resolve any objections that the FAA may have.

First germanium laser New results from MIT’s Electronic Materials Research Group bring us closer to computers that use light instead of electricity to move data.
GLAS (the Geoscience Laser Altimeter System) is the first laser-ranging (lidar) instrument for continuous global observations of Earth, which will make unique atmospheric observations as an important component of the ESE climate change program. GLAS is a facility instrument designed to measure ice-sheet topography and associated temporal changes, cloud and atmospheric properties.and give us information on the height and thickness of radiatively important cloud layers which is needed for accurate short term climate and weather prediction. In addition, operation of GLAS over land and water will provide along-track topography.
Researchers at MIT Lincoln Laboratory have created the most powerful coherently combined diode lasers yet demonstrated. These lasers address a long-standing challenge for laser technology—merging multiple laser beams coherently to produce a single-beam, high-brightness output.
