High intensity line lasers at 355-1064nm see use in a number of modern production processes, including ablation, polymer welding and solar cell processing. For applications such as these, laser intensities of more than 50mJ/cm2 at pulse durations of 10-20ns over a line of length 100mm or more are often required. Single mode lasers are unable to provide high enough pulse energies when spread over such long lines, while multi-mode lasers have higher intensities but cannot be focussed to a narrow...
