The possibiltiy to scale the output parameters of ocillators by using multiple gain media is explored and different approaches on a modular setup were tested. In this scheme, the total pump power that is needed to scale the pulse energy can be enhanced without accumulating too much heat in a single crystal. Operating the system with cavity-dumping enables high outcoupling ratios, whereas the reduced repetition rate will lead to even higher pulse energies. Due to beneficial properties like a high thermal conductivity and a large bandwith, Yb:CALGO is choosen as gain material.
