Product Family Description

  • Ultrafast-Enhanced Silver Coating for Ti:sapphire and Yb:doped Lasers
  • Low Group Delay Dispersion of 0 ±20fs2 @ 600 - 1050nm
  • <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 coating providing >99% reflectivity from 600 - 1050nm while maintaining a low group delay dispersion (GDD) of 0 ±20fs2. 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.
