Abstract
A laser treatment apparatus for determining that the output power of a treatment laser beam is proper in accordance with the selected output power. The treatment apparatus comprises a laser source for generating a treatment laser pulse beam, a laser optical path for guiding the treatment laser pulse beam toward an object to be treated, a power setting means for controlling the laser source to set the power output of the treatment laser pulse beam, and a radiation switch for selectively switching the laser source on and off. A safety device is provided to cause the laser source to output a checking laser pulse beam prior to actual transmission of the treatment laser pulse beam and at a time after the activation of the radiation switch. The checking laser pulse beam has a power corresponding to the actual power of the treatment laser pulse beam to be outputted by the laser source. A power detector detects the power output of the checking laser pulse beam and a comparator determines whether the power output of the checking laser pulse beam is correct in view of the power of the treatment laser pulse beam set by the power setting means.
