The Bios and Photonics West exhibitions are considered by many to be one of the leading American trade fairs for optical technologies and this year’s event, which took place in the Moscone Center in San Francisco, was no exception. It attracted a record attendance of over 20,000 visitors, and provided Barcelona-based lasertech manufacturer Radiantis with the perfect platform on which to showcase its newly developed OPOs, covering the continuous wave and femtosecond ranges.
