1. A test fixture for containing a duo of fore and aft test samples that forms a sample pair by said samples contacting each other along an interface, said fixture receiving exposure to laser emission for radiative heating of said fore test sample while providing compression to said sample pair and comprising:
a housing having an axial cavity with annular cross-sections including an internal helical thread portion and a window for receiving the laser emission for exposure to the fore test sample;
an isolation container for receiving the sample pair, said container being inserted into said axial cavity and including an opening for disposition adjacent to said window; and
a compressor with circular cross-sections for insertion into said axial cavity and including an external helical thread portion for engaging said internal helical thread portion of said housing, wherein axial pressure is applied to said aft test sample of said sample pair by turning said compressor inside said axial cavity.
