Cheese take three

Another use for that old laser you have lying around:

Li and his co-worker Hongseok Choi and assessed the suitability of an ultraviolet laser for cutting and drilling slices of mild cheddar that were a few millimeters thick. Central to the study was the investigation of which wavelength and energy fluence give the best results.

Experiments with the third (355 nm) and fourth (266 nm) harmonics of a Q-switched Nd:YAG laser demonstrated that a 266 nm beam is undoubtedly the preferred choice.....

To date, the team has focused on making high quality intricate cuts in 2.5 mm thick mild cheddar....
