50.8mm Dia. x 190.6mm EFL, 600-1000nm Ultrafast-Enhanced Silver Coated, 50Å OAP Mirror

Product Details Ultrafast-Enhanced Silver Coating for Ti:sapphire and Yb:doped Lasers Low Group Delay Dispersion <50Å RMS Surface Roughness to Minimize Scatter TECHSPEC Ultrafast-Enhanced Silver Coated Off-Axis Parabolic (OAP) Mirrors are used to collimate or focus incident light at a specified offset angle. These mirrors are coated with an ultrafast-enhanced silver coatings which provide a >99% reflectivity while maintaining a low group delay dispersion (GDD) of 0 ±20fs 2 at their design wavelength range. The off-axis design of these mirrors separates the focal point from the beam path, allowing for more interactive space around the focal point without disrupting the incident beam. TECHSPEC Ultrafast-Enhanced Silver Coated OAP Mirrors are ideal for focusing laser light from low-to-medium power ultrafast lasers, including Ti:sapphire and Yb:doped fiber lasers, while minimizing the temporal spreading of the ultrafast pulses. Mounting plates with holes perpendicular to the optical axis are available for mounting these mirrors into benchtop systems.
