Laser miliatary aviation, due to the potential to temporarily distract or blind pilots. See Lasers and aviation safety for more on this topic. Laser A laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation. The term "laser" originated as an acronym for "light amplification by stimulated emission of radiation". The first laser was built in 1960 by Theodore H. Maiman at Hughes Research Laboratories, based on theoretical work by Charles Hard Townes and Arthur Leonard Schawlow. A laser differs from other sources of light in that it emits light
TEA laser on to a variety of packaging materials by passing the laser light through a mask containing the information, and focusing it down to an intensity which ablates the material to be marked. Beside this TEA CO lasers are used for surface preparation in industrial environments since the mid 90’s. Applications include: The advantage of this specific laser is the combination of the CO specific wavelength, mainly 10.6 µm, with the high energy level of the short pulses (~2 μs). TEA laser A TEA laser is a gas laser energized by a high voltage electrical discharge in a gas mixture generally
