摘要

Abstract

We demonstrate collinear phase matching of transient coherent Stokes Raman scattering (CSRS) in strained diamond

enabling generation of intense

high-quality

femtosecond THz pulses over a gapless frequency band from 5 to beyond 15 THz. Our experimental results confirm this mechanism

supported by the theoretical calculations that agrees well with measurements. The theoretical model also provides a clear picture on how the input pulses should be adjusted to optimize the THz output from a diamond of given length.
