Dr. Helmut Kessler of Manx Precision Optics (MPO) presented a talk entitled “High LIDT, Low GDD Coatings for High Power Ultrafast Lasers” at the Optical Society (OSA) Laser Application Conference on 5 October 2021. Coatings for ultrafast lasers require a high Laser-Induced Damage Threshold (LIDT) and good Group Delay Dispersion (GDD) performance. This additional demand creates … Continue reading
Manx Precision Optics (MPO) has just released a new Technical Note explaining the fundamentals of growing films for optical coatings. Even though the bulk properties of the coating material meet the specifications, the final microstructure is highly dependent upon the intricacies of the film growth process. Issues such as the temperature of deposition, the crystalline … Continue reading
Chroma Technology presents a video entitled, “Sputtering of Optical Coatings: How Reactive Magnetron Sputter Coating Enables Complex Filter Design and Precision Manufacturing”. Two members of Chroma’s staff, Product Engineer John Atkinson and Director of Marketing Jeff Carmichael, discuss how various forms of high-energy sputtering are used for complex types of hard-coated spectral filters, requiring very … Continue reading
