Our capabilities does not end with the abovementioned crystals growth. We also are capable of design and development of custom laser gain and optical modules, state-of-the-art monolithic crystal assemblies and damaged crystals refurbishment service. This is realized together with scientific and industrial partners through numerous government, industry and internally funded R&D contracts.
For damaged crystals we provide cost-effective crystal refurbishment service, including repolishing, recoating, and characterization.
Repolishing of laser, nonlinear and photorefractive crystals:
- Size up to 50mm
- Surface quality up to 10-5 S-D
- Surface flatness up to λ/10@632,8 nm (for 6x6 mm and smaller crystals)
- Coatings on request
Features
- Fast delivery from 1 week
- Repolishing & resizing
