Air-cooled laser device having l-shaped heat-transfer member with radiating fins

An air-cooled laser device having a laser diode module as a light emitting source or an excitation light source, the air-cooled laser device comprises:

• a heat-receiving plate substantially horizontally-arranged, on which the laser diode module is mounted so as to be thermally connected to the heat-receiving plate;
• at least one L-shaped heat-transferring member attached to an inside or a surface of the heat-receiving plate, the L-shaped heat-transferring member extending in a surface direction of the heat-receiving plate and bending at a substantially right angle outside the heat-receiving plate so as to extend in a substantially upward vertical direction;
• a plurality of heat radiating fins attached to a substantially vertical portion of the L-shaped heat-transferring member so that each of the plurality of heat radiating fins extends in a substantially horizontal direction;
• and
• an axial fan for sending air to an upper space of the heat-receiving plate through between the plurality of heat radiating fins,
• wherein air after flowing through between the plurality of heat radiating fins cools a heating component other than the laser diode module, the heating component being positioned in the upper space of the heat-receiving plate.
