The drive towards higher power lasers in optical applications is pushing the limits of optical coating technology. However, an alternate solution for handling higher power beams is to increase beam diameter, which requires larger optical components. This decreases the power or energy density across the optical components, reducing the likelihood of laser-induced damage. Large beam expansion optics and focusing lenses further down the beam path are required. Light collection systems are another driver for increasing optics size.
