We report on a diode pumped ultrafast amplifier based on Yb:CaF2 delivering 32 mJ, at a repetition rate of up to 200 Hz, with a central wavelength of 1030nm. The pulses have spectral bandwidth of 5.5 nm, supporting a theoretical pulse duration of 250 fs, are compressed to 300 fs in a compressor based on reflection gratings with a transmission efficiency up to 89%. This laser source constitutes an ideal source for pumping nonlinear crystals through Optical Parametric Amplification or Optical rectification. It is also well adapted for seeding ultrafast high energy amplifiers based on Yb:YAG crystals
