✦ Synopsis

The in uence of the conversion of pump light of wavelengths below 400 nm into pump light with a central wavelength of 500 nm in a Europium doped quartzglass pump chamber has been investigated. The results are compared to the ones from an undoped quartzglass. The measurements resulted in a reduction of the slope e ciency by a factor of two for the doped quartzglass compared to the undoped one. Furthermore, the pump-pulse lengths around 80 s lead to a decrease in the slope e ciency compared to pump-pulse lengths above 100 s.
