Plasmas generated by focusing ultrashort laser pulses in air emit broadband microwaves. We present calibrated comparisons between the frequency spectrum of radiation from 2–70 GHz due to single and… (More)
Optimum slit design applied by the gray-tone photolithography with protrusion and diagonal has been established by simulation and experiments. The adoption of protrusion and diagonal are able to… (More)
We observe efficient narrowband terahertz emission at 15 THz from lithium niobate crystals when irradiated by femtosecond Ti:sapphire laser pulses. This emission arises from phase-matched optical… (More)

We demonstrate high-energy terahertz generation from a large-aperture (75-mm diameter) lithium niobate wafer by using a femtosecond laser with energy up to 2 J. This scheme utilizes optical… (More)
We demonstrate a single-shot scheme in characterizing terahertz spectrum by using a microbolometer focal plane array. This method measures THz field autocorrelations and can characterize THz… (More)
