Coherent Corp. introduced a product line of diffractive optical elements (DOEs) for high-power industrial lasers. The DOEs are available with precision optical coatings that ensure high reliability in kilowatt-class industrial lasers for a wide range of applications, including welding, cutting and additive manufacturing. DOEs allow industrial laser designers to combine multiple optical functions into one optical element, greatly simplifying system-level assembly. Such capabilities translate into lower cost of ownership and greater reliability, due to the lower number of parts, greater ease of optical alignment and lower number of failure mechanisms over time.
