In XWS sources light is produced by plasma which emits light due to the continuous energy input from a laser (optical discharge). These light sources have been developed as a replacement of traditional gas discharge lamps (Deuterium-, Tungsten-, Xenon- lamps etc.) and LEDs. Compared to these, XWS sources have a wider spectral range and higher spectral brightness. Moreover, the technology of plasma light sources allows developing units with specific characteristics which match special customer applications.

XWS - laser pumped plasma broadband light
source.
In XWS sources light is produced by plasma
which emits light due to the continuous
energy input from a laser (optical dis-
charge). These light sources have been
developed as a replacement of tradi-
tional gas discharge lamps (Deuterium-,
Tungsten-, Xenon- lamps etc.) and LEDs.
Compared to these, XWS sources have a
wider spectral range and higher spectral
brightness. Moreover, the technology of
plasma light sources allows developing
units with specific characteristics which
match special customer applications.
Main advantages:
▪ broad spectral range; XWS-65 light
source is available in 2 configura-
tions. The Ozone-free configuration
offers a spectral range from 240nm to
2700nm. The UV configuration offers a
spectral range from 180nm to 2700nm.
A broad spectral range allows sub-
stituting several conventional light
sources
▪ high spectral brightness;
▪ high temporal and spatial stability;
▪ the small dimensions of the emitting
volume considerably expand the range
of XWS applications;
▪ long operation, due to no wear of
lamps and electrodes.
Principle of operation:
Operation of XWS sources is based on
a phenomenon of optical discharge in
high pressure xenon. Initial plasma is
produced by a high voltage electrical
discharge in xenon. Plasma state of xenon
is sustained by a focused continuous
laser radiation.
Compared to arc lamps, laser plasma has
higher spatial and temporal stability,
higher brightness, smaller dimensions of
emitting volume and considerably longer
operation without lamp replacement.
