Abstract :
A machining station has been set up using a Q-switched INNOSLAB laser (wavelength: 532 nm; pulse length: 16 ns, pulse repetition frequency: 1 to 100 kHz ) for inverse laser drilling of transparent materials . Tests to improve the drilling depth, speed and reliability of the process as well as the influence of the glass material are being examined at present.
