Latest Patents

Wei Lu holds a patent for "High damage threshold and highly reliable broad-band mid-IR coatings for high power fluoride fiber laser." This invention provides a process for fabricating broadband anti-reflective (AR) coatings specifically designed for mid-IR fluoride fiber lasers. The AR coating consists of multiple pairs of Lithium fluoride (LiF) and AlO, deposited using electron beam physical vapor deposition at low temperatures below 60° C. The coating demonstrates a reflectivity of less than 1-1.5% in the wavelength range of 1.5-5.5 μm. The laser induced damage threshold (LIDT) test indicates a damage threshold greater than 8.9 MW/cm², with no visible damage to the coating when exposed to atmospheric conditions. The durability tests reveal good humidity resistance and no degradation in film quality or optical performance.
