Product catalog summary

Ultrafast Laser Output Coupler Mirrors

Specifications: The mirrors are made from BK 7, grade A, precision annealed optical glass. They have a surface flatness of S1, S2 ≤λ/10 at 632.8 nm over the clear aperture, with a surface quality of 15-5 scratch-dig. The diameter tolerance is +0/-0.13, and thickness tolerance is ±0.25 mm. The wedge is 30 ±15 arc min, and chamfers are 0.25-0.76 mm face width x 45° ±15°.
Performance: The mirrors have a 12% transmission and 88% reflectivity within the 720–890 nm range. The angle of incidence is 0–10°.
Coatings: S1 Coating is OC.20 with Rs, Rp = 88% ±2.5%, 720–890 nm, 0–10° AOI. S2 Coating is AR.16 broadband, multilayer antireflection coating with Ravg <0.5%, Rmax <1.5%, 650–1000 nm, 0–15° AOI.
Durability and Cleaning: The mirrors meet MIL-C-675C standards for moderate abrasion. Non-abrasive cleaning methods using acetone or isopropyl alcohol on lens tissue are recommended.
Models and Dimensions: Two models are available: 05B20-01OC.20 with a diameter of 12.7 mm and 10B20-01OC.20 with a diameter of 25.4 mm, both with a thickness of 3.00 mm.
Applications: These mirrors are designed for laser cavity output coupling in the 720–890 nm wavelength range, minimizing pulse dispersion and reducing secondary reflections.

Our OC.20 coating and the 3-mm thickness of the substrate are carefully designed and manufactured to deliver minimum pulse dispersion and wide bandwidth. A broadband antireflection coating on the second surface of the output coupler reduces unwanted secondary reflections. 12.7 and 25.4 mm diameters are available.
