Figure 6
A far-field image of the transmitted beam as measured on a high-resolution sCMOS camera (ANDOR Zyla 4.2, 6.5 µm pixel size) coupled with a 10× magnification optical element and a 10 µm-thick LuAG:Ce fluorescence screen. The camera was positioned at 1.12 m from the focal plane and the beam fills the whole camera field of view. The scale bar refers to the camera dimensions. The uniform distribution of intensity is an indication of the great quality of the KB mirror surfaces. |
