Abstract
The apparatus has diode lasers (2,4) which emit laser radiation with different central wavelength. The laser radiations from diode lasers are superimposed with each other. A control device (12) is provided for controlling laser power of diode laser. The thermal coagulation process is performed with respect to simultaneous emission of laser radiation from diode laser in processing mode. The ratio of laser power of diode laser in processing mode is changed according to specific pattern and/or as a function of detected process signal over predetermined time.
