A solar-pumped laser (or solar-powered laser) is a laser that shares the same optical properties as conventional lasers such as emitting a beam consisting of coherent electromagnetic radiation which can reach high power, but which uses solar radiation for pumping the lasing medium.
The High Energy Laser with Integrated Optical-dazzler and Surveillance ( HELIOS) is a 60 kW+ high energy laser designed to intercept aerial threats such as drones, missiles, and other airborne targets and even small boats. It was designed and manufactured by Lockheed Martin, which was awarded a contract to design such a weapon in January 2018.
Since even relatively small amounts of laser light can lead to permanent eye injuries, the sale and usage of lasers is typically subject to government regulations. Moderate and high-power lasers are potentially hazardous because they can burn the retina , or even the skin.
Carbon-dioxide lasers are the highest-power continuous-wave lasers that are currently available. They are also quite efficient: the ratio of output power to pump power can be as large as 20%. The CO 2 laser produces a beam of infrared light with the principal wavelength bands centering on 9.6 and 10.6 micrometers (μm).
High power applications, such as hardening, cladding, and deep penetrating welding, require multiple kW of optical power, and are used in a broad range of industrial processes. Micro material processing is a category that includes all laser material processing applications under 1 kilowatt. [12]
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.
