Optimized Coherence

Optimized Coherence

Laser applications that depend on interference are incredibly diverse today – from semiconductor inspection to LIGO gravitational-wave observatories. They all depend on long coherence, narrow linewidth, and low-noise. But just how narrow and how quiet varies greatly. Similarly, the wavelength and power requirements are often quite different for each application. Coherent supports this reality with the world’s broadest offering of single-frequency lasers, drawing on our unmatched technology breadth.
