Low GDD ultrafast laser mirrors designed for use with Yb:YAG (515nm, 1030nm), Yb:KYW (1030nm), and Yb:KGW (1030nm) diode-pumped solid-state lasers (DPSSL) and laser systems.

  • Ion beam sputtered (IBS) coating perfect for demanding laser applications.
  • Reflection > 99.9% available as 0° and 45° AOI options. 
  • Low Group delay dispersion (GDD) < 20 fs2 ideal for ultrafast pulse lasers.
  • High laser damage threshold (LDT).
  • Advanced option with superior LDT for improved optic lifetime.  
  • Stress compensating coating (SCC) to improve the surface flatness.
  • Precision <20/10 surface quality to minimise scattering.

A stress compensating coating (SCC) can be applied to side 2 to increase the surface accuracy, this would generate a 4-6 week lead time. 

Custom low GDD ultrafast laser line mirrors are also available upon request with custom sizes between 3 to 250mm and coating wavelength ranges between 200-5000nm. Contact us with your product enquiry.
