==Excimer Laser==

A Lambda Physik EMG 101 argon fluorine (ArF) excimer laser (shown in Figure 2) with an operating wavelength of 193 nm was used to ablate single-crystal CVD diamond. The laser is capable of delivering 120 mJ at a maximum repetition rate of 50 Hz and pulse duration of 20 nanoseconds. The pulse geometry is an asymmetrical flat top Gaussian with horizontal dimensions of 22 mm and vertical dimensions of 6 mm.

This particular laser shown in Figure 2 was over 30 years old when we first acquired it for the project. Much of my time (maybe too much :) ) has been spent restoring it so that it could maintain high energy levels for extended periods of time. All of my troubles are explicitly detailed in my logbooks which can be shared on request.
