Photo of the week: Fire and Ice.

by on Feb.26, 2014, under Projects

During the winter one of the members tried carving ice with the laser, with the intent to capture a little bit of Game of Thrones in ice.
This may sound both a great idea and a bad idea at the same time. The act of doing some test cutting proved this task to be more difficult than previously thought. Below you can see the results of the test cuts. The challenge was not water inside the laser, that was a simple challenge to overcome by adding a reservoir for any water that was melted and a mesh to keep the ice out of the water. The challenge with this came to be the laser itself. The power of the laser on the ice is just a bit too much for this job. This experiment became a practical demonstration of the effect of hot spots on ice in the Arctic.
The Laser is equal to the sun here, and when it heats up the ice enough for it to melt it basically creates a warm pool of water that melts the surrounding area of ice preventing any high resolution cutting. The more heated water the less of ice that remained. The laser job had to be stopped a few times to remove the excess water to achieve some of the quality of the cut in the second photo.
