Deposition Sciences, Inc. (DSI), global manufacturer of highly durable thin film optical coatings, introducesa new line of high laser damage threshold (LDT) coatings. Designed for use with lasers and other high energy systems, thesecoatings are ideal for diode, diode-pumped solid-state (DPSS), and gas lasers. DSI’s new products feature laser damage threshold levels as high as 25 MW/cm2

High laser damage threshold performance is coupled with the company’s unique, field-proven ability to uniformly coat a wide variety of component geometries, including complex shapes. For example, DSI’s new low insertion loss coatings feature extremely low reflectance with anAR coating performance rating of R< 0.25 percent, according to Dr. Michael Newell, Director of Sales and Marketing.

Dr. Newell reports, “DSI has successfully deployed the new line of LDT coatings in a variety of critical applications, with components such as micro lenses, fiber lenses, collimators, beam shaping optics, ball lenses, hemispherical lenses, LED lenses, and even domes and reflectors. Our specialized IsoDyn low-pressure chemical vapor deposition (LPCVD) process gives us a unique capability to provide excellent performance and high laser damage thresholds for laser systems. Our customers are excited by the high level of performance our new LDT coatings deliver.” 

High damage thresholds are extremely critical for many of today’s laser applications, including laser cutting, laser machining, micromachining, laser drilling, and laser welding.
