IPG Photonics GLPN-40-1-20-M
Nanosecond laser for precision laser scribing and cutting.
Our workhorse for laser cutting and scribing with high precision four-axis stage and a high-performance galvanometer scanner for repeatable µm accuracy at high speed.
Investigations into the application of lasers for micromachining of silicon are also being carried out, including the drilling and scribing of deep vias and trenches and the initiation of crystal plane selective silicon etching. Rapid creation of deep features with minimal micro-cracking or laser induced damage is relevant to various complex solar cell designs, and also allows for the utilisation of various test structures that can be used for characterision of laser and other solar cell fabrication processes.
