A blue laser emits electromagnetic radiation with a wavelength between 400 and 500 nanometers, which the human eye sees in the visible spectrum as blue or violet. [1] Blue lasers can be produced by: direct, inorganic diode semiconductor lasers based on quantum wells of gallium (III) nitride at 380-417nm [2] [3] or indium gallium nitride at 450 ...

BELLA (laser) The Berkeley Lab Laser Accelerator ( BELLA) is a laser built by the Thales Group and owned and operated by the Lawrence Berkeley National Laboratory. [1] [2] On 20 July 2012, BELLA fired a 40 femtosecond laser pulse, establishing a world record for most powerful laser. [2] [3]
The carbon-dioxide laser ( CO2 laser) was one of the earliest gas lasers to be developed. It was invented by Kumar Patel of Bell Labs in 1964 [1] and is still one of the most useful types of laser. Carbon-dioxide lasers are the highest-power continuous-wave lasers that are currently available. They are also quite efficient: the ratio of output ...

Laser cutting. Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. While typically used for industrial manufacturing applications, it is now used by schools, small businesses, architecture, and hobbyists. Laser cutting works by directing the output of a high-power laser most commonly through optics.
