Hollow Waveguide

Caption: This image depicts the experimental setup used to create a coherent version of the Roentgen tube in the soft X-ray region of the spectrum. When a long-wavelength, femtosecond laser is focused into this hollow waveguide filled with high-pressure helium gas, part of the laser is converted into an ultrafast, laser-like, X-ray beam.
