The Lightblade Learning Lab with Russ Sadler
The Lightblade Learning Lab is a series of videos that Russ did for Thinklaser Limited based on using the Lightblade 4060 Laser Cutting and Engraving Machine. Thinklasers Lightblade 4060 has a 400 x 600mm bed size and was supplied with a 60W EFR laser tube. In this session, Russ explains the interaction of the laser beam and materials and answers the following question: So, how do lasers work?
- Different damage thresholds for materials.
- The ways that a laser beam cuts and engraves different materials.
- The beam in cross-section.
- Test firing the laser at a piece of wood and looking at the effect.
- Heating organic materials leaving carbon.
- Result of firing a beam at an organic block.
- Colour temperatures and absolute zero.
- Effect of a beam on a surface – reflections and ‘absorption’, i.e. stimulation of the surface atoms.
- Effect of focusing the beam.
- Focused beam tests and effect on the time.
- Effect of longer pulses.
- Ideally cut with highest power as quickly as possible.
