Technology and experimental study on roll texturing with pulse RF CO2laser

The equipment for roll texturing is developed based on RF CO2 laser, which has a lot of advantages as easy modulation of laser pulse, compacted configuration, low - cost for implement, operation and maintaining. Effects of the technology parameters to laser texture are studied in experiments. With appropriate assist gas pressure and reasonable defocus, results show that the remarkable effects on the size and shape of textured spots are the frequency, width of laser pulse and the velocity of process.
