abstract = "Subpicosecond time-resolved Raman spectroscopy has been used to measure the lifetime of the LO phonon mode in GaN at T = 300K for photoexcited electron-hole pair density ranging from 1016cm-3 to 2×019c/w-3. The lifetime has been found to decrease from 2.5 ps, at the lowest density to 0.35 ps, at the highest density. Our experimental findings should help resolve the recent controversy over the lifetime of LO phonon mode in GaN.",
