Abstract :
A novel pump source, generating 1 ps pulses with an envisaged pulse energy of 50 J and 10 Hz, is planned. Here we present our progress in the implementation of an existing diode-pumped Yb:YAG MOPA system as the first stages of the final PFS CPA pump laser. This CPA pump laser is seeded by a fraction of a Ti:Sa-oscillator which gets spectrally shifted in a photonic-crystal fiber. In the following zero-dispersion stretcher, a spatial light modulator (SLM) enables spectral amplitude shaping of the pulses and hence suppress the effect of gain narrowing in the subsequent Yb:YAG amplifiers.
