Table-top optical driver

Caption

Fig. 1: (a) Table-top optical driver generating femtosecond mid-infrared pulses at a wavelength of 5 μm. Nonlinear ZnGeP_2 (ZGP) crystals serve for pulse amplification. (b) Copper tape target for X-ray generation, placed in a vacuum chamber. The intense mid-infrared pulses (red dashed arrow) are focused onto a 20 μm thick copper tape (intercept point of blue x-ray arrows). The copper tape is moved at a velocity of 5 cm/s to provide a fresh target area for each driver pulse. The plastic tapes serve for collection of metallic debris from the target and move in parallel.
