Mainly for curved surfaces, complex surface parts and components of ultra-fine cold processing etching, the use of femtosecond laser etching equipment for ITO, FTO, zinc oxide, zirconium oxide, titanium oxide, nickel oxide NiOx, gold, silver, carbon powder and other conductive metals, oxide materials laser etching, can achieve high temperature alloys, metals, non-metals, especially composite materials surface microstructural machining, but also for the glass, silicon wafer, Zirconia ceramics and other materials, ultra-fine line width laser etching, scribing, grooving.
