…gas, greatly extending their lifetime for both cleaning and replacement. As a result of these efforts, a close to 1 J/pulse XeCl laser now has a maximum repetition rate of 600 Hz (which represents a factor of two increase in just one year) and a typical tube lifetime of 4-5 billion pulses. The typical…

…in Photonik 3/2007 Figure 4: Compressed pulse from a Micra-5 fs oscillator near to the transform limit. The pulseduration measured here is 10.4 fs Figure 5: Pulse manipulation of a Micra oscillator for CARS - spectroscopy. The results are two coherent pulses with almost identical bandwidth and intensity…

…, referred to as pulse widths, can be any length less than 1000 µs, although the actual laser discharge may not respond to very short pulse widths. Incoming pulse widths longer than 1000 µs will be automatically limited by the RF amplifier. In addition, the duty cycle of pulsing must not exceed a…

…µs after ns-pulsed KrF excimer laser irradiation ( = 248 nm) at fluence of 1.6 J cm-2 pulse-1 . [1] These images were taken by the use of a timedelayed flashlight at 560 nm with the duration of 20 ns from a Rhodamine-dye solution, which was excited by the irradiation of an ns-pulsed XeCl excimer laser…

…thyratron lifetimes of a billion pulses. Thyratron based pulsed excimer lasers doubtlessly offer advantages for mostly scientific low to moderate repetition rate applications. Especially the relatively small time delay between electrical trigger signal and emitted light pulse associated with very low temporal…

…resulting in a socalled chirped pulse with non transform-limited time duration: a red-shifted leading edge and a blue-shifted trailing edge. This propagation effect is not overly important with 150 fs to 200 fs pulses, but it becomes very noticeable with pulsedurations of just 75 fs. If left unchecked…

…-adjust fiber coupling. Experiments on the 308-nm fiber delivery for more than 2.5 million laser pulses 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 to be different for individual samples of optical fibers that perform…
