As Covesion’s products are so well documented, we were able to easily select the waveguide we needed and discussions with Covesion’s team were helpful and clear. The product works well and is used regularly by the team here at IDQ.

The exceptional customer service from Covesion not only made the purchasing experience smooth and effortless but also instilled confidence in the quality and reliability of their products. Their dedication to customer satisfaction truly set them apart and made them a trusted partner for us.

Compared to some other nonlinear mediums, Covesion’s PPLN product provides much higher nonlinear coefficient and good optical qualities that are suitable for high power laser applications.

Covesion has good reputation in the community, they provide good quality products as well as excellent technical support for the materials and technologies used in our laser system. They offer a range of standard in-stock products, together with providing bespoke products and customised services.

The cooperation with our partners Covesion and Fraunhofer IPM during the project and beyond was excellent. It enabled us to achieve results beyond the planned objectives.
