By collecting the light emitted from the induced plasma plume and directing into a spectrometer the measured lines can then be correlated with the presence and concentrations of the samples elemental structure. DPSS high pulse . The output specifications can be chosen according to our customers needs, mainly by choice of the seed laser (multiple seed lasers are possible) and various options available. aeroPULSE is our ultrafast fiber laser platform. This increased HAZ is undesirable, as post processing (cleaning) is then required, and furthermore, depending on the requirements and specifications of the material or product, significant heat build up can cause catastrophic failure of the part, its particular features, or simply render it unusable, for example with medical products that need clean, smooth features.
