Title :
Colliding quasiparticles with intense terahertz fields
Author_Institution :
Univ. of California Santa Barbara, Santa Barbara, CA, USA
Abstract :
Strong quasi-cw terahertz fields accelerate and recollide electron-hole pairs injected by a near-ir laser into GaAs quantum wells. A frequency comb is emitted, with up to 18 teeth separated by twice the terahertz frequency.
