Abstract

A laser treatment apparatus which performs a medical or surgical treatment using laser-beam irradiation, The apparatus has a solid-state laser medium for obtaining a laser beam and an excitation light source for exciting the solid-state laser medium. The apparatus further has a first optical system having a Q-switch which emits light oscillated by the solid-state laser medium as a pulse wave laser beam, and a second optical system which emits the light oscillated by the solid-state laser medium as a continuous wave laser beam. An optical path for the light oscillated by the solid-state laser medium is switched to one of optical paths of the first and second optical systems. With this apparatus, plural oscillation modes and wavelengths can be switched over in accordance with the treatment object, and the load on the user is reduced.
