The World's Smallest Jigsaw Puzzle Piece

An anonymous reader writes "Scientists from the Laser Zentrum Hannover used a femtosecond laser to make what is probably the world's smallest jigsaw which will be shown at the Hannover Messe. Its size is 5mm x 5mm and it consists of 100 parts. It's supposed to demonstrate the precision with which femtosecond lasers can cut materials without burning or damaging them.

Well its half a centimeter along each edge obviously.

With 10 pieces along each edge, (If you look at the picture they are pretty much square) then each piece has the width of 0.05cm or 0.0005m which for me is pretty tiny.

But the most impressive thing is that the laser is able to cut this substance while not destroying it.
