Fourier Limited Picosecond Pulses for Laser Cooling of Relativistic Ion Beams — •Daniel Kiefer and Thomas Walther — Technische Universität Darmstadt, Institut für Angewandte Physik, Laser und Quantenoptik, Schlossgartenstr. 7, 64289, Darmstadt

Laser cooling of relativistic ion beams has been shown to be a sophisticated technology [1] and white light cooling has been demonstrated in non-relativistic ion beam cooling [2]. However, the experimental realisation of white-light-cooling of relativistic beams still has to be performed. The necessary laser bandwidth shall be provided by pulsed laser light. Simulations have shown the demanding requirements for these laser pulses [3]. We present a master-oscillator-power-amplifier system supplying laser pulses of 100 to 740 ps length with a centre wavelength of 1029 nm. The system is marked by the Fourier transform limited character of the pulses, the continuously adjustable pulse length and the repetition rate between 500 kHz and 10 MHz. [1] S.
