摘要

This device for cutting brittle members such as glass is provided with: a laser oscillator configured to irradiate a laser through a first space onto a first region of the aforementioned member; a cooling nozzle configured to spray a coolant onto a second region different from the first region; a baffle which, arranged so as to form a gap at the member and so as to be placed in a state not enclosing the first space, is oriented so as to deflect from the first space the flow of droplets and water vapor from the second region; and a gas nozzle configured so as to spray a gas towards the gap.
