…of the XeCl excimer laser and benefits from a simple and easy-to-adjust fiber coupling. Experiments on the 308-nm fiber delivery for more than 2.5 million laserpulses of 8-ns pulse width (FWHM) and up to 8-mJ stabilized pulse energy are performed. The long-time pulsed UV laser transmission is found…

…allows the EPM2000 to read very longpulses with well-behaved rise characteristics. Figure 4: Determining a peak. Trigger the EPM2000 as close to the pulse as possible. If the EPM2000 is triggered too early, it will detect fluctuations in the noise preceding the pulse and derive a false peak. Features…

…melt produced when using longpulsedlasers. Irregular and incomplete melt expulsion affects the shape of the hole, produces recast layers and may even completely close a hole which was open initially. The depth which can be heated to melting temperature during a laserpulse of length is determined by…
