Broadband Laser Mirrors | Wide-Angle Ultrafast Mirrors

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.
