Temperature dependent emission and absorption cross section of Yb 3+ doped yttrium lanthanum oxide (YLO) ceramic and its application in diode pumped amplifier
2013
Temperature dependent absorption and emission cross-sections of 5at% Yb3+ doped yttrium lanthanum oxide (Yb:YLO) ceramic between 80K and 300K are presented. In addition, we report on the first demonstration of ns pulse amplification in Yb:YLO ceramic. A pulse energy of 102mJ was extracted from a multi-pass amplifier setup. The amplification bandwidth at room temperature confirms the potential of Yb:YLO ceramic for broad bandwidth amplification at cryogenic temperatures.
