Abstract

We show that a hydrothermal method-grown ZnO is a potential material of an imaging device for soft X-ray laser diagnostics. The single shot image of emission patterns originating from the Ni-like Ag ion plasma laser excitation of 13.9 nm wavelength is clear enough to monitor the evolution of the beam radius around the focal point. By plotting the emission pattern radii at each position, the beam profile of the Ni-like Ag ion plasma laser was estimated from the waist radii as 29 μm and 21 μm, the divergence angle of 7.2 mrad and 11 mrad and M2 factor of 47 and 50 in the horizontal and vertical axis, respectively. These results are consistent with the specifications of the soft X-ray laser that the radius of the light source is 25 μm, the divergence is around 10 and M2 is 50 in this experiment.
