Something OPSL, Something New
The latest optically pumped semiconductor lasers (OPSLs) enable full-color laser light shows with high electrical efficiency in large outdoor locations, even with challenging weather conditions – as proved at the wedding of Prince Albert of Monaco this summer. No royal wedding celebration is complete without a giant laser show, but that doesn’t mean pulling off such a large-scale event is as easy as choosing flowers or planning seating arrangements. When Prince Albert of...
