Since its founding in 2001, AdTech has been providing laser devices for the telecommunications, defense and medical industries. In 2005 the company advanced beyond traditional semiconductor lasers, committing itself aggressively to the very new high-tech field of QCLs. In 2008, AdTech spun out its photodiode division into D-Tech, in order to better focus its resources on the development of the emerging QC technology. At its premises in City of Industry, CA AdTech has all the necessary in-house equipment and know-how to entirely design, engineer and manufacture semiconductor laser devices. AdTech Optics is a privately owned and funded corporation employing about 35 people. In 2015, AdTech received ISO 9001:2008 certification.
