  2. Laser power scaling - Wikipedia

    en.wikipedia.org/wiki/Laser_power_scaling

    Laser power scaling. Power scaling of a laser is increasing its output power without changing the geometry, shape, or principle of operation. Power scalability is considered an important advantage in a laser design. This means it can increase power without changing outside features. Usually, power scaling requires a more powerful pump source ...

    en.wikipedia.org/wiki/Laser_2

    The Laser 2 is a sailing dinghy, built predominantly of fibreglass. It has a fractional sloop rig, a raked stem, a plumb transom, a transom-hung rudder controlled by a tiller with an extension and a retractable daggerboard. It displaces 170 lb (77 kg). The crew can make use of a single trapeze. [3] [4]

  5. Optical heterodyne detection - Wikipedia

    en.wikipedia.org/wiki/Optical_heterodyne_detection

    Optical heterodyne detection. Optical heterodyne detection is a method of extracting information encoded as modulation of the phase, frequency or both of electromagnetic radiation in the wavelength band of visible or infrared light. The light signal is compared with standard or reference light from a "local oscillator" (LO) that would have a ...

  6. Blue laser - Wikipedia

    en.wikipedia.org/wiki/Blue_laser

    A blue laser emits electromagnetic radiation with a wavelength between 400 and 500 nanometers, which the human eye sees in the visible spectrum as blue or violet. [1] Blue lasers can be produced by: direct, inorganic diode semiconductor lasers based on quantum wells of gallium (III) nitride at 380-417nm [2] [3] or indium gallium nitride at 450 ...
