What arguments support the hypothesis of the melt displacement by the vapor pressure in keyhole welding by laser beam? Why do they convince you?

There are a lot of experimental results that strongly contradict this hypothesis, as well as alternative ideas about of hydrodynamics of welding. You never thought about it?

What could be the lowest appropriate temperature to prebake thin (80 nm) PMMA e-beam resist?

I need to prebake PMMA on the sample which is degraded under high temperatures. It seems that even 1500C could kill the sample. I don't have any experience of use of PMMA prebaked under lower...

Why does the depth of laser weld increases in a vacuum?

The depth of the keyhole welding in vacuum increases sharply (in nearly 3 times) compared with atmospheric conditions. There are not very convincing assumptions, but the real reason is stiil unknown.
