Nd:YAG for Halloween

In (partly) honour of Halloween, we’ve been playing around with our Nd:YAG laser, demonstrating it to our 4th year MEng students as part of their Laser Materials Processing module. By frequency doubling it, the emission is changed from it’s standard 1064 nm wavelength to 532 nm, and we’ve focused it through a lens.

 

Suitably spooky.
