<p>A process for configuring a laser device (10) that has been set up for emitting focused pulsed laser radiation (14) and that is intended for use in laser-assisted treatments of the human eye (12) comprises the following steps: - selecting a pulse length within a range from 1 ps to 1 ns, preferentially within a range from above 10 ps to below 300 ps, - selecting a wavelength for the laser radiation within a range from 300 nm to 400 nm or within a range from 800 nm to 1100 nm, - ascertaining such a set of parameter values of the laser device that when the laser device is operated with these parameter values a two-dimensionally extensive separation of tissue of human corneal or lenticular tissue is achievable by means of the laser radiation by stringing together a plurality of local sites of damage, the set of parameter values including, in addition to the selected pulse length and the selected wavelength, values for at least one of the following parameters: a pulse energy, a pulse repetition rate, a fluence per radiation pulse, a number of pulses per site of damage, a scanning speed of a scanning apparatus (18) of the laser device, a focus diameter, - configuring the laser device in such a manner that operation of the laser device with the ascertained set of parameter values is made possible.</p> |
