Lasers are classified to the degree of hazard they represent, determined by the Maximum Permissible Exposure (MPE) What is MPE? This is the highest power or energy density of a light source that is considered safe. It is 10% of the dose that has a 50% chance of creating damage under worst-case conditions. Class 1 Lasers 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… lithium battery trade show
