Abstract
A laser apparatus () has a semiconductor laser device (to), coolant jetting means (), and a heatsink (to). The semiconductor laser device has a light output surface () for emitting laser light. The coolant jetting means has a coolant chamber () for accommodating a coolant, an inflow port () communicating with the coolant chamber, and a jet port () opposing the light output surface of the laser device. The heatsink has a laser mount surface () for mounting the semiconductor laser device, and a flow path (to) where the coolant () jetted from the jet port flows in. When the coolant chamber is fed with the coolant, the jet port jets the coolant onto the light output surface of the semiconductor laser device. Since the light output surface is directly cooled by a jet flow of the coolant, cooling efficiency is excellent.
