| Popis: | Indirectly induced laser lift-off occurs at the interface of a transparent film and an underlying absorbing substrate. Induced laser ablation often referred to as “laser lift-off” is much more energy efficient than direct laser writing. In this paper we report on the selective laser structuring of copper-indium-diselenide (CIS) film on a molybdenum layer at a wavelength of 1342 nm with nanosecond pulses by indirectly induced laser ablation. A wavelength of 1342 nm was chosen, because the CIS layer can act as a transparent film there and this wavelength can be generated with industrial reliability by a laser transition in Nd:Vanadate. |
