800-1150nm, 50.8mm Dia. x 150mm EFL, Ultrafast-Enhanced Silver Concave Mirror

Product Details Ideal for Focusing Ti:sapphire and Yb:doped Laser Pulses Reflectivity >99% at 600 – 1000nm or 800 – 1150nm Low Group Delay Dispersion as Low as 0 ±20fs 2 Effective Focal Lengths from 25 to 500mm TECHSPEC Ultrafast-Enhanced Silver Laser Mirrors Available TECHSPEC Ultrafast-Enhanced Silver Concave Laser Mirrors feature silver coatings that are enhanced with a dielectric coating to provide increased reflectivity at 600 – 1000nm or 800 – 1150nm. These mirrors have an intrinsically low group delay dispersion (GDD) across their wavelength range, making them ideal for focusing or redirecting laser light from femtosecond lasers such as Ti:sapphire and Yb:doped lasers. Their broad wavelength range allows them to be used in applications that require a larger bandwidth than dielectric coated low GDD mirrors can provide. TECHSPEC Ultrafast-Enhanced Silver Concave Laser Mirrors are available in standard imperial sizes and with effective focal lengths up to 500mm. Note: TECHSPEC Ultrafast-Enhanced Silver Concave Laser Mirrors can be designed with different wavelength ranges for other ultrafast laser types.
