Amplification of 26 fs, 2 TW pulses in Ti:sapphire
- Washington State Univ., Pullman, WA (United States). Dept. of Physics
Applications of high intensity physics including ultrafast x-ray generation, short-wavelength lasers, extreme-ultraviolet harmonic generation, and multiphoton ionization require not only very high peak power excitation, but also benefit from short excitation pulse durations. Chirped pulse amplification (CPA) has been proven to be a useful method for generating ultrashort pulses with peak powers up to the terawatt level and beyond, and with {approx} 100 fs pulse durations. In the past, the amplified pulse durations were limited by the duration of the dye or solid-state laser oscillators used to generate the seed pulses, and by the presence of uncompensated higher-order dispersion in the amplifier. However, it is now feasible to routinely generate optical pulses as short as 10 fs in duration using self-mode locked (SML) Ti:sapphire lasers. Here, the authors have demonstrated a simple multipass amplifier system that generates pulses as short as 26 fs in duration, with an energy of > 60 mJ per pulse. The design minimizes higher-order dispersion and spectral distortions, and results in a near-transform limited 2 TW peak power output.
