Lasertel Focus

Within our vertically integrated semiconductor laser manufacturing facility, we have rapidly expanded our product portfolio and development of innovative QCW and CW array stack technology.

Lasertel continues to grow through the addition of expertise in electronics, thermal management and software development, resulting in facility expansion to produce sub-assemblies and turn-key systems. Most recently, medical laser systems and laser diodes for autonomous vehicles serve as a large focus for Lasertel.
