Laser apparatus

Abstract

A laser apparatus which is capable of terminating a irradiating operation using a laser beam without fail by opening switches even if a component of an irradiation switch unit have trouble during the irradiating operation in a continuous irradiation mode. A first switch (11) and a second switch (12) are connected electrically in series by signal lines (18) and are disposed in a side-by-side arrangement. An operating member (13) is a pedal for a foot switch or the like and is capable of substantially simultaneously closing and opening the first switch (11) and the second switch (12) in substantially the same degree. The irradiation switch unit may further be provided with a cover (16) for covering the operating member (13). In a continuous irradiation mode or the like in which a laser beam can be emitted for a time equal to or nearly equal to a time interval in which the irradiation switch unit are operated, a laser beam can be emitted only when both the first switch (11) and the second switch (12) are turned on.
