Laser science awarded the Nobel Prize in Physics in 2018 for groundbreaking inventions in the field of laser physics. The first working laser (a pulsed ruby laser) was demonstrated on May 16, 1960, by Theodore Maiman at the Hughes Research Laboratories. Laser science Laser science or laser physics is a branch of optics that describes the theory and practice of lasers. Laser science is principally concerned with quantum electronics, laser construction, optical cavity design, the physics of producing a population inversion in laser media, and the temporal evolution of the light field in the laser. It is also concerned with the physics
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
