Many industrial and scientific applications need ultra-short pulses with high average power. Diode-pumped systems based on ytterbium-doped crystals have a huge interest thanks to their good thermal and spectroscopic properties. Among them, Yb:CALGO and Yb:CaF2, hold exceptional positions exhibiting a very atypical combination of ultrabroad bandwidth and high thermal conductivity, therefore very promising for short pulse and high power applications. In this paper we present an overview of the results obtained with these two crystals. First, we detail the origin of this exceptional gathering of their broad emission bands and good thermal properties. Second, we present the results obtained in femtosecond regime with these two crystals including a discussion on the actual limitations of Yb-doped ultrafast solid-state lasers.
