Notes:
We built and characterized an instrument to measure the output profile of a pulsed KrF laser. The laser beam is focused onto a ∼1-mm-thick fluorescer, and the resulting fluorescence is imaged by a charge coupled device (CCD) camera. We tested 21 materials for efficiency, linearity, and fidelity. The best material is Schott BG-26 color filter glass. It has acceptable linearity for a fluence of 50 mJ/cm2, and a spatial resolution of ∼50 μm with a laser convergence angle of 30° (F/2), when the fluorescence is imaged with F/3 optics. We present a list of the materials tested and comparisons of profiles measured by using the fluorescer and by direct recording with a CCD camera. © 2001 American Institute of Physics.
