Configuration is selected and carefully tuned according to a specific laser micromachining application.

Femtosecond micromachining. Femtosecond laser micromachining system femtofab is a turnkey laser machine designed for specific industrial process. Newer femtosecond laser machine option solves common working distance challenge for micromachining and mold texturing. Lasers have become an indispensable tool for moldmakers who have used the technology to achieve textures and precision beyond the capabilities of traditional milling or edm machines. The ultrashort pulse laser machining systems were developed to. The use of micromachining femtosecond laser. Femtosecond laser micromachining was first demonstrated in 1994 when a femtosecond laser was used to ablate micrometre sized features on silica and silver surfaces 12in less than ten years the. Femtosecond lasers have overcome these problems and high quality micromachining is now possible6 in a range of bulk metals as shown in figure 1. Femtosecond lasers produce very high peak pulse powers which in turn drive non linear multiphoton absorption in the material. The other recent development which has affected the area of metal micromachining is the development of high repetition. Spark laser is an ultrafast fiber laser manufacturer operating in the us australia uk and ireland france germany switzerland israel korea japan and china. In the more than two decades since a team of researchers from the center for ultrafast optical science at the university of michigan first demonstrated the use of a femtosecond laser for micromachining 1 this technology has clearly made its evolutionary step from scientific equipment to a reliable. The pico and femtosecond laser micromachining has grown up as a reliable tool for precise manufacturing and electronic industries to make fine drilling and machining into hard metals and ceramics as well as soft plastic and to form various nano and microtextures for improvement of surface functions and properties in products. Laser micromachining technologies have revolutionized manufacturing in microelectronics semiconductor photovoltaics led medical device fabrication and many other industries. Microtexturization of the surface of an implant that was experimented to enhance bone formation in the dental implants is among the femtosecond laser applications. The femtosecond laser can process virtually any material even if it is transparent such as glass.

We also offer micromachining femtosecond laser applications for precise cutting results. Unlike traditional linear absorption this is less dependent upon wavelength.
