For High-Power Lasers, Thin Is Cool

Adolf Giesen, University Stuttgart, Institute Strahlwerkzeuge

High-power diode-pumped solid-state lasers promise to provide small, versatile, rugged light sources for applications from the factory to the cleanroom. Commercial devices that take advantage of the latest generation of high-power diodes can produce tens of watts for industrial and scientific applications. Producing higher powers in a compact device is problematic. As their power increases, so does the temperature inside the laser cavity. This produces an effect known as thermal lensing, which degrades the quality of the laser beam. Ultrahigh-power (kilowatts) solid-state lasers minimize the...Read full article
