  • Page 21: Laser Description

    Laser description SuperK Extreme lasers are a series of white light lasers (WLL) systems that can generate a pulsed supercontinuum as a class 4 laser source. Using a 78 Mhz seed laser, light frequencies from 400 to 2400 nanometers (typical) are emitted in a single spatially coherent beam with a pulse rate that is customizable according to application requirements.
