Abstract: A control device that can apply a laser oscillator control device to various types of systems. The control device includes an analog signal input unit configured to receive an output control signal for controlling a laser output of the laser oscillator or a mode control signal for controlling an operation mode of the laser oscillator as an analog signal; a digital signal input unit configured to receive the output control signal or the mode control signal as a digital signal; and a controller configured to transmit a laser command for controlling the laser output to the laser oscillator in response to the output control signal received by the analog signal input unit or the digital signal input unit, and transmit an operation command for operating the laser oscillator to the laser oscillator in the operation mode in response to the mode control signal received by the analog signal input unit or the digital signal input unit.

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.

Abstract: A first calculation unit calculates an acceleration factor of lifetime consumption of the light source with as case of a standard temperature and standard drive condition as a reference, a second calculation unit calculates a whole lifetime or remaining lifetime of individual light sources relative to a performance index of the individual light sources or a change rate of the performance index, a computation unit obtains an effective cumulative driving time at which the magnitude of influence imparted on the lifetime is equivalent with a case of driving at the standard temperature and standard drive condition, by calculating a time integral of the acceleration factor, and a recording unit records the effective cumulative driving time and the whole lifetime or remaining lifetime together with an optical output characteristic of the light source.
