“
The customer service from Covesion has always been excellent. We have a great rapport with Corin (ProfessorCorin Gawith, CTO, Covesion) and the team, and their knowledge is invaluable. I have had occasion to use Covesion crystals twice during my research at The University of Glasgow and the turnaround for the custom products was very quick, meaning the research could continue without delay.
Specifically with regards to our area of interest, the PPLN crystals are periodically poled, and the period of poling needs to be optimised to ensure the best performance of the source, enhancing the efficiency of the generation. Covesion gave us various options rather than just one specific period for the poling. For example, in one of the devices there were different groups of poling periods and that allowed us to optimise for best performance and find the configuration that worked the best.
