Paper Abstract

The optical excitation of the I6 level in Yb:Ho:YLF is studied. Pumping with a wavelength of 953 urn populates the 2F572 upper level of yi3+fromwhere the energy is efficiently transferred to the '6upper laser level ofHo3. Pumping is performed with a Ti:sapphire laser. Based on the measured rise times and decay times of the fluorescence from the y3 2F level, the Ho3 5S2 and '6 levels the cross relaxation coefficients w yi3+ 2F512 + Ho3 '8 —3 y132F712 + Ho3 '6), w (Ho3I6+ Ho3 '6 Ho3 5S2 +Ho3 '8) and w 2F512 + Ho3I8 y3 2F712 + Ho3 5S2) as well as the ESA cross-section o6 (Ho3 '6 — H35S2) are estimated with the aid of a numerical analysis
