We propose an original optical architecture for the construction of an Integrated Dumper - Regenerative Amplifier, by combining pulse generation and pulse slicing together with downstream regenerative amplification within a common amplifying unit and resonator. This design provides relatively short pulses at high energy, using a fairly simple and robust two-path resonator. The demonstration is performed with the help of a diode-pumped Yb(3+): YAG slab operated at room temperature at 1Hz PRF, in the energy range of 5 to 50mJ per pulse with 500ps to 5ns FWHM.
