The invention relates to a method for testing a laser device (10) which is designed to provide focused, pulsed laser radiation, the focus position (18) of which can be varied both in and perpendicular to the direction of propagation of the laser radiation. The laser device comprises a contact element (30) which is transparent to the laser radiation and has a bearing surface (34) on which an object to be treated is placed. In the course of the method, a test object (36) which is transparent to laser radiation in at least one treatment area is placed against the bearing surface of the contact element. Laser radiation is then directed inside the test object that rests on the bearing surface, and the focus position is moved in accordance with a predefined test pattern in order to produce permanent treatment structures in the test object.
