Abstract
A laser treatment apparatus for performing treatment on a treatment part of a skin by irradiating the part with a laser beam for treatment is disclosed. The apparatus includes: a window having an optical property of transmitting the treatment beam, the window being brought into contact with the skin for laser irradiation; a window cooling unit; a contact-state detector which detects a contact state of the window with the skin; and a controller which changes a cooling control temperature of the cooling unit from a predetermined first temperature which is previously set higher than 0° C. to a predetermined second temperature lower than the first temperature when the contact-state detector detects that the window is in contact with the skin.
