An absorption-reduced planar waveguide structure is proposed for increasing the efficiency of
terahertz (THz) pulse generation by optical rectification of femtosecond laser pulses with tiltedpulse-
front in highly nonlinear materials with large absorption coefficient. The structure functions
as waveguide both for the optical pump and the generated THz radiation. Most of the THz power
propagates inside the cladding with low THz absorption, thereby reducing losses and leading to the
enhancement of the THz generation efficiency by up to more than one order of magnitude, as
compared with a bulk medium. Such a source can be suitable for highly efficient THz pulse generation
pumped by low-energy (nJ-lJ) pulses at high (MHz) repetition rates delivered by compact
fiber lasers.
