LASER DEVICE AND METHOD FOR OPERATING A LASER DEVICE

摘要

It is provided a laser device comprising an operating laser for providing an operating light at an operating wavelength and a safety light source for providing a safety light mainly at a safety wavelength, wherein the safety light source is coupled such to the operating laser that the safety light is directed in the same direction like the operating laser during operation of the operating laser, wherein the safety wavelength is better absorbable by melanopsin than the operating wavelength. According to the invention the increased safety is not provided by adjusting the power of the emitted light but by using the human eyelid closure reflex by stimulating the melanopsin of the light-sensitive ganglion cells on the retina of the human eye.
