The transformations of the two known solid phases of HTaWO6, pyrochlore and trirutile, under visible light laser irradiation, have been investigated using Raman spectroscopy. Pyrochlore specimens show a transition to a trirutile phase after strong irradiation in air. The same effect is also obtained by heating up to 700°C. A more moderate irradiation of pyrochlore samples in an oxygen-free environment produces a different transformation to a phase similar to Ta2O5. The trirutile phase always decomposes, even under weak light exposure, into two compounds: WO3 and another material also similar to Ta2O5
