WebManufacturers often classify their laser products using an international standard. Under the International Electrotechnical Commission (IEC) Standard 60825-1, laser products are categorized in the following order, from the lowest to highest potential risk: Class 1, 1M, 2, 2M, 3R, 3B and 4. Lasers are distinguished from other light sources by their coherence. Spatial (or transverse) coherence is typically expressed through the output being a narrow beam, which is diffraction-limited. Laser beams can be focused to very tiny spots, achieving a very high irradiance, or they can have a very low divergence to concentrate their power at a great distance. Temporal (or longitudinal) coherence implies a polarized wave at a single frequency, whose phase is correlate…
