Optically pumped semiconductor lasers at Coherent: a historical perspective

Over twenty years ago Coherent introduced the first products based on the then novel Optically Pumped Semiconductor Laser Technology (OPSL). Since then, OPS lasers have found application in a variety of fields and today Coherent offers a full product line based on the technology. In this presentation we'll cover the history of the development, from laboratory demonstrations to commercial success. We'll describe some of the technical hurdles that we overcame along the way and discuss advantages and disadvantages of the technology in the marketplace as well as other practical considerations.
