Hi Kenneth,

ZnSe is particularly tricky. We model dielectrics which have large gap energy compared to photon energy so the initial absorption mechanism is MPA followed by electronic avalanche. We have a few papers on this, all of them are on my google scholar page, have a look. Our modelling is limited to electromagnetics including plasma resulting in a steady electron cloud which eventually recombine to produce an instant (compared to heat transfer times) excess of material temperature. We don't do further modelling of material modification.

Regards,

Vladimir
