Wide-angle laser line 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. Our broadband laser line mirrors work between 700-900nm, ideal for Ti:Sapphire lasers. 

  • Ion beam sputtered (IBS) coating perfect for demanding laser applications.
  • Reflection > 99.9%.
  • Our wide-angle laser line mirrors work between 0-45°.
  • Group delay dispersion < 30 fs2 ideal for ultrafast pulse lasers, especially Ti:Sapphire lasers where pulse broadening can be an issue. 
  • High laser damage threshold (LDT).
  • Stress compensating coating (SCC) to improve the surface flatness.

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

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.
