Paper Abstract
Transmission, absorption and laser induced fluorescence (LIF) measurements were performed to reveal the applicability
of different grade CaF2 for 248 nm laser applications. No emission from self-trapped excitions could be found in LIF
measurements after irradiation with 100k pulses for all grades. Therefore, three-photon excitation could be excluded up
to 1 J/cm2. Whereas emission at 420 nm and partially the double-peak at 313/333 nm could be found in LIF
measurements. UV-VIS difference spectra did not show any absorption bands after 248 nm irradiation of the samples.
Optical elements from CaF2 promise high life expectancy at 248 nm if a standard laser polish is used and hot spots are
avoided.
