How to increase the dry etch resistance of PMMA?

I have some patterns made on PMMA resist with electron beam lithography. When I try to etch the substrate using dry etching, the PMMA is getting removed very fast. How to increase the dry etch...

Is there any scaling law for mass ablated by irradiating a ns laser at different fluences?

When a high power laser irradiates a solid surface, material is ablated to form plasma. The mass ablated may depend on fluence, wavelength of laser, target material, etc., Is there any scaling...
