  3. Solar-pumped laser - Wikipedia

    en.wikipedia.org/wiki/Solar-pumped_laser

    A solar-pumped laser (or solar-powered laser) is a laser that shares the same optical properties as conventional lasers such as emitting a beam consisting of coherent electromagnetic radiation which can reach high power, but which uses solar radiation for pumping the lasing medium.

    en.wikipedia.org/wiki/Carbon-dioxide_laser

    Because of the high power levels available (combined with reasonable cost for the laser), CO 2 lasers are frequently used in industrial applications for cutting and welding, while lower power level lasers are used for engraving. In selective laser sintering, CO 2 lasers are used to fuse particles of plastic powder into parts.

  5. 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 ...

    Laser rods (from left to right): Ruby, alexandrite, Er:YAG, Nd:YAG. A solid-state laser is a laser that uses a gain medium that is a solid, rather than a liquid as in dye lasers or a gas as in gas lasers. [1] Semiconductor -based lasers are also in the solid state, but are generally considered as a separate class from solid-state lasers, called ...
