Highly-Dispersive Ultrafast Mirrors for Dispersion Compensation
Learn how Highly-Dispersive Mirrors compensate for dispersion and compress pulse duration in ultrafast laser systems, which is critical for maximizing performance.
The short pulse durations of ultrafast lasers lead to broad wavelength bandwidths, making ultrafast systems especially susceptible to dispersion and pulse broadening.
Mounting flat mirrors by their edges in a kinematic mount imparts stress onto the mirror surface. This results in distortion and reduced quality of the reflected wavefront, which is especially noticeable when using high-quality mirrors. Stemmed mirrors, on the other hand, are mounted from a smaller diameter “stem” protruding from the back of the mirror, resulting in significantly reduced stress on the mirror surface, high stability, and cost reduction and can be used as a replacement for a more expensive and complex kinematic mount and a conventional mirror.
Ultrafast highly-dispersive mirrors are critical for pulse compression and dispersion compensation in ultrafast laser applications, improving system performance.
Schwarz Mirrors minimize unwanted stray light using an opaque, engineered fused silica substrate that absorbs light that would otherwise be transmitted.
Superpolished optical surfaces minimize scatter and improve performance in highly sensitive optical applications. Learn how they are made and measured.
I would like to use your Off-Axis Mirror in a laser application with high temperatures. What is the maximum damage threshold and temperature limit these mirrors can withstand?
Ultrafast lasers have revolutionized a number of application spaces, but optical components for these systems face a unique set of challenges that must be overcome to maintain high pulse quality and maximize performance.
Edmund Optics' panel of laser optics experts discuss why the industry standard of measuring transmission to infer the reflectivity of high reflectivity laser mirrors doesn’t tell the whole story.
