Burn holes in paper depicting the spatial uniformity of our laser pulse energy. There are 4 rows, each containing 6 to 7 burn holes obtained using the pulse energy shown to the right. It is apparent from the second row that it is not possible to make the beam energy profile entirely uniform. The pulse duration is 7 msec and the burn holes are ~ 2 mm in diameter. The paper was positioned by hand; consequently the slight scatter in the position of the holes has no significance.
