AB  - We report on the development of a 2 MHz non collinear optical parametric 
      amplifier (NOPA) for high repetition rate time resolved X-ray or optical 
      spectroscopy. Our modular and very flexible device is pumped by the second and 
      third harmonics of a commercial femtosecond Ytterbium-doped fiber laser. The 
      amplified pulses are tunable from 520 nm to 1000 nm with pulse durations between 
      15 and 30 fs over the full tuning range. The same setup is also suitable for 
      broadband amplification and we demonstrate the generation of 6 fs pulses at a 
      central wavelength of 850 nm as well as the generation of a broadband spectrum 
      supporting 4.2 fs transform limited pulse duration at a central wavelength of 570 
      nm. Very high stability and compactness is achieved thanks to an optimized 
      mechanical design.
