AB  - We report on a high repetition rate noncollinear optical parametric amplifier 
      system (NOPA) based on a cavity dumped Ti:Sapphire oscillator providing the 
      signal, and an Ytterbium-doped fiber amplifier pumping the device. Temporally 
      synchronized NOPA pump pulses are created via soliton generation in a highly 
      nonlinear photonic crystal fiber. This soliton is fiber amplified to high 
      pulse-energies at high repetition rates. The broadband Ti:Sapphire laser pulses 
      are parametrically amplified either directly or after additional spectral 
      broadening. The approach of fiber-based pump-pulse generation from a femtosecond 
      laser, that emits in the spectral region of NOPA-gain, offers enhanced long-term 
      stability and pulse quality compared to conventional techniques, such as signal 
      pulse generation from a high power laser system via filamentation in bulk media. 
      The presented system produces high-energy ultra-short pulses with pulse-durations 
      down to 15.6 fs and pulse-energies up to 500 nJ at a repetition rate as high as 2 
      MHz.
