A simple technique is described giving information concerning the energy profile of a Q-spoiled laser beam. The method, which employs a number of foils each consisting of 1
3 × 10-6 cm of aluminium deposited on transparent terylene sheet, is suitable for lasers having an output in excess of approximately 02 J. Experimental results obtained with the authors' laser are described, and it is shown that the total area of aluminium removed is proportional to the energy in the laser pulse and is 134 ± 015 cm2 J-1 (47 ± 05 μg J-1) for the foil used, provided the energy density is greater than 06 J cm-2.
About 94% of the incident energy is reflected by the foils, which must, therefore, be screened to protect personnel.
