YAG rods, reflectors, plastics and “O” rings. They are particularly well suited for laser pumping applications.

Cerium Doped Quartz Flashlamps

The UV transmission properties of quartz can be modified by the incorporation of a dopant. This dopant is most often cerium or titanium oxides. The quartz still appears clear but the UV transmission has been modified. This modification is desirable when potentially damaging UV from the flashlamp must be eliminated. This includes the elimination of ozone or the prevention of UV damage to Nd:YAG rods, reflectors, plastics and “O” rings. Cerium-doped quartz has significant applications in flashlamps for laser pumping. The UV cut off at approximately 380 nanometers ensures that harmful UV is eliminated from the pump chamber.

Excelitas is the premier flashlamp producer in the world for a wide range of applications. We actively participate in the advancement of flash lamp technology through extensive research in materials, technology and production processes.

The UV absorption is accompanied by fluorescence in the visible spectrum and an increase in laser efficiency can be expected as some of it falls in the absorption bands of Nd:YAG.

Cerium doped quartz has very stable material properties throughout lamp life making it a very desirable envelope material for flashlamps.

Excelitas takes pride in providing solid state and Xenon-based lighting products and solutions that help to create a brighter, healthier and safer environment.
