Laser Rod Repolishing

BJP can repolish and coat most laser gain crystals, including:

1. Nd:YAG
2. Cr⁴⁺:YAG
3. Er:YAG
4. Yb:YAG
5. Nd:Ce:YAG

Services include core drilling, cutting, centerless grinding, polishing and coating. BJP can provide convex or concave radii on rod ends, as well as wedged ends or tilted ends. Slab repolishing is also available.
Most of the anti-reflection, high reflector, partial reflector or dichroic coatings can be applied to laser rods. We can also produce a wide range of custom coatings.
Standard anti-reflection coatings for the most popular laser crystals have the foll- owing reflectance specifications:

Standard refurbishing specifications:

Parallism ≤10 arc seconds
Perpendicularity ≤5 arc minutes
Surface Quality 10/5 Scratch / Dige MIL-O-13830A
Suface flatness < λ/10 @ 632.8 nm
Dimensional tolerances Diameter: +0/-0.05mm Length: ±0.5mm Chamfer : <0.1 mm @ 45º
Clear Aperture Central 95%
AR-Coating Reflectivity ≤ 0.15% (@1064nm
