We report a relaxation study of elementary excitations in heavily underdoped Bi 2 Sr 2 CaCu 2 O 8+d (Bi2212) using picosecond Raman Spectroscopy. In B 1g symmetry, the two-magnon peak shows a super-linear power dependence which is ascribed to excess magnon population. In contrast, the broad feature
