摘要：
Multifunctional laser device for processing material, particularly biological material (30), with a laser light source (1), which supplies light with a wavelength, which corresponds to a wavelength of a high absorption coefficient of more than 10 cm-1 of the material to be processed, providing the laser light source with light pulses with a corresponding pulse duration and pulse repetition frequency, characterized in that the laser light source is at least one laser diode (1 ) powered by a controllable power supply (10, 20), because the power supply comprises a control installation (10), which is configured to control at least one laser diode (1) with modifiable current and allows a rapid modification of the wavelength, the control installation (10) being configured to control the current at least one laser diode (1), such that a modification is obtained n of the wavelength in an operating wavelength range, which comprises the wavelength of at least one interval with an essential modification of the material's absorption coefficient and why the light pulses have an energy that is found between one and twenty times the threshold energy of the material for a withdrawal and a repetition frequency in the range of more than 300 Hz.Dispositivo láser multifuncional para el procesamiento de material, particularmente material biológico (30), con una fuente de luz láser (1), que suministra luz con una longitud de onda, que se corresponde con una longitud de onda de un coeficiente de absorción alto de más de 10 cm-1 del material a procesar, suministrando la fuente de luz láser impulsos de luz con una duración de impulso y una frecuencia de repetición de impulso correspondientes, caracterizado por que la fuente de luz láser es al menos un diodo láser (1) alimentado por un suministro de corriente (10, 20) controlable, por que el suministro de corriente comprende una instalación de control (10), que está configurada para el control del al menos un diodo láser (1) con corriente mo
