The cooling controller controls a cooling operation according to data associated with a heating state of a laser light source in the laser device.
First claim
Opening claim text (preview).
What is claimed is: 1. A cooling device to cool a laser light source of a laser device to irradiate a medium with a laser beam, the cooling device comprising: a cooling controller to control a cooling operation of the cooling device according to data associated with a heating state of the laser device obtained without employment of a sensor; and a fan, operatively connected to the cooling controller, to cool the laser light source, wherein the laser device is an image forming…
