Humankind has always been fascinated by light and has long relied on it also (for supporting life, for communications, for entertainment etc). But beyond that, manipulated appropriately, it becomes a tool like no other. It is fast, precise, sterile, selective and highly energetic. It delivers unique processes and materials of unparalleled qualities.
