Coherent Emission from the Nonpolar Optical Phonon of Diamond
Cornelius Beckh, Niklas Fritzsche, Alfred Leitenstorfer
Emission of a coherent field transient from optical phonons in monocrystalline diamond is observed after impulsive femtosecond excitation. Measurements on an extremely pure sample suggest a monoatomic layer of surface dipoles as a leading source for this subtle effect.
