Laser laser devices. The question of just how to assign credit for inventing the laser remains unresolved by historians. On May 16, 1960, Theodore H. Maiman operated the first functioning laser at Hughes Research Laboratories, Malibu, California, ahead of several research teams, including those of Townes, at Columbia University, Arthur Schawlow, at Bell Labs, and Gould, at the TRG (Technical Research Group) company. Maiman's functional laser used a solid-state flashlamp-pumped synthetic ruby crystal to produce red laser light, at 694 nanometers wavelength; however, the device only was capable of pulsed operation, because of its three-level pumping design scheme. Later that year,
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).
