Abstract:
A transparent medium processing device comprising:a light source section for generating a laser beam with a wavelength which has transparency with respect to a processing target, wherein said light source section is a pulse laser light source for generating pulse laser beams having femto-second pulse width; a light control section for executing a variable control for the status of the laser beam emitted from said light source section, wherein said light control section includes a spatial form shaping section for shaping a spatial form of a laser beam; an incident optical system section for entering the laser beam controlled by said light control section to the processing target; and a light status measurement section for measuring the status of the laser beam inside the processing target; wherein said light control section is adjusted based on the output of said light status measurement section so that the status of the laser beam inside the processing target becomes a desired status, the processing target being the transparent medium, thereby the laser beam status inside the transparent medium is fed back to said light control section.
