Abstract: A machine learning device acquires decision data including an adjustment time of a position and an orientation of an optical part and a state of light measured by a light measurement device. The machine learning device includes a learning unit that learns a procedure for adjusting the position and the orientation of the optical part. The learning unit includes a reward calculation unit that calculates a reward based on the alignment adjustment time and the state of light, and a value function updating unit that updates a value function based on the reward. The learning unit includes a decision unit that sets a movement method of the optical part based on the value function.

Abstract: An optical absorber includes a first light-absorbing body which receives light incident from an entrance aperture and partially absorbs and reflects the incident light, and a second light-absorbing body which partially absorbs the incident light reflected by the first light-absorbing body and partially reflects the incident light toward the first light-absorbing body. The reflectance and light resistance of the first light-absorbing body are set higher than the reflectance and light resistance, respectively, of the second light-absorbing body.

Abstract: A laser oscillator which can estimate the rotation speed of a blower in an idle state at cheaper cost and higher precision. The laser oscillator is comprised of a resonator part, laser medium flow path, blower, drive part, controller, manometer which measures the pressure of the laser medium at a predetermined position of the laser medium flow path, and rotation speed estimating part which uses the pressure of the laser medium which is measured by the manometer and a predetermined relationship between the pressure of the laser medium and the blower rotation speed at a certain position as the basis to estimate the rotation speed of the blower. The controller controls the drive part so as to restart operation of the blower at the rotation speed which is estimated by the rotation speed estimating part when the power supply to the blower is stopped and the blower is idling.
