  2. Laser cutting - Wikipedia

    en.wikipedia.org/wiki/Laser_cutting

    Diagram of a laser cutter Laser cutting process on a sheet of steel CAD (top) and stainless steel laser-cut part (bottom) Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. While typically used for industrial manufacturing applications, it is now used by schools, small businesses, architecture, and ...

  3. Laser beam profiler - Wikipedia

    en.wikipedia.org/wiki/Laser_beam_profiler

    Changes in the pump laser beam profile indicate the health of the pump laser, which laser modes are excited in the gain crystal, and also determine whether the laser is warmed up by locating the centroid of the beam relative to the breadboard. The output beam profile is often a strong function of pump power due to thermo-optical effects in the ...

  4. Laser beam machining - Wikipedia

    en.wikipedia.org/wiki/Laser_beam_machining

    where t is the depth of cut, P is the laser beam power, v is the cutting velocity, and d is the laser beam spot diameter. [5] The depth of the cut is also influenced by the workpiece material. The material's reflectivity, density, specific heat, and melting point temperature all contribute to the lasers ability to cut the workpiece.

  5. M squared - Wikipedia

    en.wikipedia.org/wiki/M_squared

    M 2 is useful because it reflects how well a collimated laser beam can be focused to a small spot, or how well a divergent laser source can be collimated. It is a better guide to beam quality than Gaussian appearance because there are many cases in which a beam can look Gaussian, yet have an M 2 value far from unity. [1]

  6. Laser beam quality - Wikipedia

    en.wikipedia.org/wiki/Laser_Beam_Quality

    Laser beam quality studies commenced in the 1960s, following the discovery of the laser. [1] The M (mode) factor was introduced to experimentally measure the presence of higher-order modes within a Gaussian-like beam.
