Abstract
For the laser machining of organic materials, a laser with the below listed parameters is used. The laser has a wavelength of 300 nm to 1200 nm, a pulse width of <50 ns and a pulse frequency of >20 kHz. To increase a degree of absorption and consequently the machining rate, additives with good absorption of the laser beam with the respectively chosen wavelength are admixed with the organic materials.
