摘要：

A two-dimensional detector array has been fabricated from a single 10-mm-diam by 100-mum-thick chemical vapor deposition diamond disk by applying a 1x1 mm(2) metallization grid of 4x4 pixels with centered bias connections. This diamond has been exposed to high power pulsed laser radiation. It has been shown that this kind of diamond array operates as a radiation hard, ultrafast laser beam profiler and can obtain spatial profiles with 500 ps temporal resolution. Ten spatial profiles were obtained within a single 5 ns duration laser pulse, revealing in detail the temporal and spatial development of the laser beam intensity. No attenuation is necessary for this profiler when making single-shot measurements at intensities up to similar to 100 MW/cm(2). (C) 2002 American Institute of Physics.
