Light with a wavelength shorter than 200 nm. This is used as a secondary cooling device for water-cooled YAG lasers.Ī laser that uses carbon dioxide as a medium and oscillates at a typical wavelength of 10.6 microns.Īn air-cooling method that uses radiator fins, fans, and Peltier elements to cool down laser equipment.
Instrument to measure the distribution of intensity for laser beam.Ī device that chills water and keeps it at a fixed temperature. Normally, this is used to specify the value of a beam center at half its peak value.Īn angular measurement of a beam diameter's growth as it leaves the oscillator.Ī cross-sectional graph of a laser beam's power distribution. Generally speaking, this refers to the diameter of a laser beam.
Since the primary marking beam is invisible, alignment beams are useful for visually confirming alignment.Ī device that refines the center of a laser beam by only allowing a specific diameter of laser light to pass through.ĪR is an abbreviation for Anti Reflection.Īn AR coating is applied to the laser lens to prevent reflections from occurring on the lens' surface, thus improving the transmittance of the laser beam.Īn optical component or shutter that is used to adjust the intensity or power of the laser. This page provides easy-to-understand explanations of common laser marking terms.Īn acousto-optic method Q-switch that changes the refractive index of light by introducing ultrasonic waves.Īlignment beams are auxiliary laser beams used to display the position of the primary marking beam and perform position adjustments.
