Abstract
A laser treatment apparatus for performing treatments on an affected part by irradiating the affected part with a laser beam for treatment is disclosed. This apparatus includes a laser oscillator, a cooling unit including a fan which cools the laser oscillator, a temperature sensor which directly or indirectly detects a temperature of the laser oscillator, and a control unit which drives the fan at roughly constant low speed when a detected temperature by the temperature sensor is below a predetermined reference value and at roughly constant high speed when the detected temperature is the predetermined reference value or more.
