Excitation of coherent optical phonons in iron garnet by femtosecond laser pulses
Pritam Khan, Masataka Kanamaru, Wei-Hung Hsu +4
We employed femtosecond pump probe technique to investigate the dynamics of coherent optical phonons in iron garnet. A phenomenological symmetry-based consideration reveals that os…
