…therefore is one with a pulse duration of less than 10's of picoseconds. Nanosecond laser pulses are too long to produce good spallation results, even at ultraviolet wavelengths, and the high cost of femtosecond lasers (vs. picosecond) is not justified by any advantage for spallation. Pulse repetition rate is…

…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 pulse durations of just 75 fs. If left unchecked…

…The laser pulses need to be capable of selectively removing thin film layers <0.5 µm thick with minimal Heat Affected Zone (HAZ) and surface debris. Hence, the high quality features produced by short picosecond pulse durations [8], [9] are of interest for LCD repair. Using such laser pulses ensures that…
