I try to calculate laser ablation of tungsten with first and third harmonic of Nd-YAG laser.
Only data I found in [1] are at room temperature.

On the other hand I know that reflection coefficient is changing dramaticly with increasing of temperature.
Did you find the reference in http://refractiveindex.info/?shelf=main&book=W&page=Rakic It is very useful.
In our group we do pump probe measurements on reflectivity of other metals, see e.g Ultrafast pump-probe microscopy reveals the mechanism of selective fs laser structuring of transparent thin films for maskless micropatterning.
or: Time and space resolved microscopy of induced ablation with ultrashort laser pulses.
