In XWS sources, the interaction between a continuous wave laser and high pressure xenon gas, which creates an optical discharge and broad bandwidth light is emitted as a result. The xenon gas is maintained in its plasma state by focused laser irradiation. These CW light sources have been developed as a replacement for traditional gas discharge lamps (Xenon, Deuterium, Tungsten, etc.) and LEDs. Compared to these sources, the XWS-65 has a wider spectral range and higher spectral brightness.
