Abstract
The transparent medium processing device comprises: a light control section for performing variable control for the status of the laser beam emitted from the light source section , and a light status measurement section for measuring the status of the laser beam inside the processing target TG. The light control section is adjusted based on the output of the light status measurement section so that the status of the laser beam inside the processing target becomes a desired status. Since the status of the laser beam inside the processing target, which is made of such a transparent medium as glass, is measured by the light status measurement section, and is fed back to the light control section, laser processing can be executed while maintaining an optimum status at a processing point inside the processing target.
