Abstract
Even when a light source is driven under various conditions, an effective driving time is accurately calculated. A laser apparatus includes a light source, a power source which charges driving current to the light source, a control unit for controlling the power source, a first recording unit which calculates a life load rate of the light source and records the same in association with time, and a calculation unit which calculates, as an effective driving time, a time integration of the life load rate between a first time point, at which the laser apparatus is actually driven, and a second time point after the first time point, based on a recording result of the first recording unit.
