History
Lasag, an industry leader for laser cutting, welding and marking, was founded in 1974.  In 2010, Lasag joined the Rofin-Sinar Group.  This allowed Lasag to become a major global presence, operating as Rofin-Lasag.  A few years later in 2016–a powerful international coalition offering cutting age laser technology and advanced materials processing was firmly established–when Rofin was acquired by the Coherent Group.
Lasag was originally established in Switzerland as a wholly-owned subsidiary of ASUAG Manufacture for drilling watch stones.  In 1976,

Lasag produced the first pulsed Nd:YAG Laser for welding applications in the electronics industry and over the next few decades established itself in new fields, including medical and aviation.  Significant in laser technology was the 1988 introduction by Lasag of a beam delivery using optical fibers for material processing.  Lasag continued to bring forth innovations in compact laser devices and pulse power-controlled sources for maximum reproducibility of seam and point welding.  In 2003, Lasag launched LightWare™, a cutting edge solution in precision laser welding.  Lasag continued to expand its market, setting up offices in Chicago, Italy, Japan and Germany.  Lasag continued to develop a series of innovative products and processes, and when it merged with the Rofin Group, a new era of compact, maintenance free welding and cutting lasers was launched.  Moreover, the product range of the Lasag processing heads was expanded to include a high-performance triple head able to cut three pieces at once.  It is worth noting that this long-established company can point to products still viable after being used for over two decades.
