In much the same way that the 20th century was dominated by the electronics revolution, the 21st century promises to be shaped by photonics - the science of light.

Until the development of the laser, all light was basically incoherent. Coherent light, by contrast, can be directed, focused and used to illuminate new possibilities well beyond the realm of its everyday, incoherent counterpart. At Coherent, Inc., that's precisely what we do.

We are one of the world's leading suppliers of photonics-based solutions to a broad range of commercial and scientific research customers. We design, manufacture and market lasers, laser-based systems, precision optics and related accessories for a diverse group of customers. Since our beginning in 1966, we have expanded our business through a combination of internal growth and the strategic acquisition of companies with related technologies.
