Determination of ablation threshold and rate for ultrafast laser machining
- Familiarisation with the Ultrafast laser and its safe operation
- Turn on the laser
- Measure laser power
- Confirm the position of the laser via visualisation techniques
- Determine the focal position of the laser
- Determine the ablation threshold for single pulse ablation
- Determine the material removal rate as a function of number of pulses
Introduction to the use of optical microscopy and white light interferometers for sample measurement and analysis
After completion of the laboratory the user should be capable of safe operation of the machines, have an understanding of the limitations of each technique, and be able to further look at standards needed for their own specific measuring needs.
