241 – 271nm, 25.4mm Dia., Ultrafast Mirror

Product Details Designed with High Reflectivity for Ultrafast Beam Steering Ion-Beam Sputtered Coating for Low Scatter and Absorption GDD as Low as 0±20fs 2 at Design Wavelength Range TECHSPEC High Performance Low GDD Ultrafast Mirrors are designed to have high reflectivity at 0° or 45° angles of incidence, making them ideal for ultrafast laser beam steering applications. These mirrors have a dispersion compensating coating obtained through a precision ion beam sputtering (IBS) process, providing lower scatter and absorption than traditional dielectric laser mirrors. TECHSPEC High Performance Low GDD Ultrafast Mirrors have a group delay dispersion (GDD) of near zero at their design wavelength range, minimizing dispersion of the reflected beam. Typical applications include use in the transport of femtosecond laser pulses. Note: Please contact us if your application requires a TECHSPEC High Performance Low GDD Ultrafast Mirror with a custom wavelength, angle, or size.
