Laser power meter, the laser output measurement method and a laser output monitoring system,

摘要

A laser power meter according to the invention is configured to have a power damper including a laser receiving body that receives a laser beam on an inner surface thereof and converts laser power into heat, a case that forms a channel between the case and an outer surface of the laser receiving body, a heat insulation member between the laser receiving body and the case, and temperature measurement means for measuring a heat quantity absorbed by the laser receiving body; and conversion means for converting a signal of the temperature measurement means into an output value for a laser beam.
