Edge cladding glass is used for active laser materials to absorb light from spontaneous and amplified spontaneous emission. These effects are reducing laser efficiency and can damage the active materials.
SCHOTT recognizes that laser customer needs are not only limited to available glasses. For this reason, SCHOTT maintains a program of custom test melting on a contract basis. In this way, SCHOTT can provide glass samples suitable for characterization of optical, physical, and laser properties, as well as for fabrication of small optics and devices allowing to take advantage of our vast glass knowledge. If requested SCHOTT will produce your glass composition.
All components are manufactured according to customers’ specifications. Depending on geometry, flatness or transmitted wavefront distortion far below λ/10 can be achieved. SCHOTT also provides anti-reflection or high-reflection coatings with a high laser-induced damage threshold.
- Quality control is based on statistical process control, as well as on rigorous final inspection of the finished component
- Glass properties are measured for every melt
- Measurement instruments include broad range of interferometers and microscope interferometers, spectro-photometers, autocollimators, physical property test systems, vision systems, and a laser test bed
