Abstract
A test device to calibrate the pulse energy of a laser device which provides pulsed laser radiation includes a measuring head with multiple measuring probes. The test device is used in such a way that by means of the laser radiation, multiple test ablations are made on a test surface, in an arrangement corresponding to the relative spatial arrangement of the measuring probes, and the depths of the test ablations are then measured, with simultaneous use of the multiple measuring probes of the measuring head.
