Giving a Green Light

Michael Watts

Green lasers have been important since the very first days of the laser. Indeed, many of the earliest applications in medicine, graphics and basic research demonstrated the versatility of green laser light, particularly from the argon-ion laser.

In the past few years, the maturation of all-solid-state green lasers has allowed engineers and product designers to expand on these early applications while creating new ones in a growing number of medical, commercial and industrial processes…
