The higher the class, the more powerful the laser and the potential to pose serious danger if used improperly. Remember, laser pointers are not toys and they should only be used by an adult, or with adult supervision. One takeaway from this is that for high-power lasers with poor M2 values, the effort to implement diffraction-limited optics is less critical, as small amounts of lens wavefront error will not significantly affect the beam divergence and image size. The light energy is converted to heat, which damages the tube-shaped sacs within the skin (hair follicles) that produce hairs. One basic type of laser consists of a sealed tube, containing a pair of mirrors, and a laser medium that is excited by some form of energy to produce visible light, or invisible ultraviolet or infrared radiation. One disadvantage of this metric is that it weighs the contributions from the wings (the low-power-density regions further away from the center of the beam) more than other methods, occasionally making the M2 factor more useful in academic settings than industrial applications. Copyright 2016 - 2023 WideLasers.com. Laser with pulse duration in nanosecond and microsecond ranges are known as short laser and for pulse duration less than 1 ps are termed as ultra-short laser [].
