MULTIFUNCTIONAL LASER DEVICE

摘要

The invention relates to a multifunctional laser device for treating material, especially biological material (30) the absorption properties of which over the operating wavelength range are considerably modified. Said laser device comprises at least one laser diode (1) which is supplied by a controllable power supply unit (10, 20), the power supply unit having a control device (10) for controlling the laser diode (1) with variable current and/or variable pulse duration and/or pulse repetition frequency. The laser light wavelength of the laser device can be quickly modified. The control device (10) for controlling the current supplied to the at least one laser diode (10) is designed in such a manner that the wavelength over an operating wavelength range is quickly modified, which wavelength includes the wavelength of at least one section the absorption coefficient of the material of which is considerably modified.
