Patent ID: 8394085

Claim:
A laser perforation apparatus that perforates skin using a laser, the apparatus comprising: a laser light source that emits a laser light; and a laser output controller that controls division of a laser output from the laser light source such that a plurality of laser lights are emitted to a same perforated position in one perforation operation, wherein the laser output controller comprises a laser light branch that branches the laser light emitted from the laser light source into a plurality of optical paths of different optical lengths and focuses the plurality of optical paths branched from the laser light on the same perforated position, the plurality of optical paths being separate until the plurality of optical paths reach the same perforated position, the laser light branch comprises a total reflection mirror that totally reflects an incident light and a splitter that transmits part of the incident light and reflects the rest of the incident light, at least one of the total reflection mirror and the splitter comprises a cubic optical device, the total reflection mirror and the splitter are positioned at predetermined angles with respect to the incident light such that the plurality of optical paths branched from the laser light reach the same perforated position in an order determined based on an optical length of each of the plurality of optical paths.
