    The High Energy Laser with Integrated Optical-dazzler and Surveillance (HELIOS) is a Lockheed Martin-developed 300 kilowatt high-energy laser weapon designed to intercept combat drones, fast-attack craft, and missiles. [1] After winning the contract in 2018, the first announced installation was on the USS Preble (DDG-88) in 2019. [2]

    The International Lubricant Standardization and Approval Committee (ILSAC) also has standards for motor oil. Introduced in 2004, GF-4 [28] applies to SAE 0W-20, 5W-20, 0W-30, 5W-30, and 10W-30 viscosity grade oils. In general, ILSAC works with API in creating the newest gasoline oil specification, with ILSAC adding an extra requirement of fuel ...

    en.wikipedia.org/wiki/Laser_engraving

    Laser engraving metal plates are manufactured with a finely polished metal, coated with an enamel paint made to be "burned off". At levels of 10 to 30 watts, excellent engravings are made as the enamel is removed quite cleanly. Much laser engraving is sold as exposed brass or silver-coated steel lettering on a black or dark-enamelled background.

    en.wikipedia.org/wiki/Ultrashort_pulse_laser

    [1] [2] Common current ultrashort pulse laser technologies include Ti-sapphire lasers and dye lasers. High output peak power usually requires chirped pulse amplification of a seed pulse from a modelocked laser. Dealing with high optical powers also needs the nonlinear optical phenomena to be taken in account. [citation needed]
