title: Avoiding the requirement for pre-existing optical contact during picosecond laser glass-to-glass welding: erratum.
abstract: The results presented in Fig. 8 were incorrect; the growth in the weld structure presented was due to the laser taking 3 ms to reach full power. Here we present a corrected version of the figure and associated discussion. It should be noted that this affects only the exact number of pulses required to form the weld structure and some of the low pulse number observations. This does not therefore affect the theory presented in the paper. In addition Fig. 9 and Fig. 10 were reversed in the published version. The correct figures are presented below.
