IRVINE, Calif., March 17, 2011 — Newport Corp. has introduced a terahertz pulse generation kit that uses a sub-35-fs Ti:sapphire amplifier system. The kit can be easily integrated with a Ti:sapphire amplifier to generate terahertz pulses that can be used for linear, nonlinear and time-resolved spectroscopy applications.
The kit uses proprietary standard optics and photonic components, optomechanics, manual stages and Conex-based motorized solutions to provide high performance and accuracy. The 800-nm Ti:sapphire laser pulse (1 kHz, ~300 µJ per pulse) is focused into ambient air to generate the air plasma that produces the terahertz pulses. With this design, the damage threshold is not a concern because the air replenishes itself from pulse to pulse.
The generated terahertz pulse produces oscillation that spans about 1 ps and estimated pulse energy of 0.1 to 0.3 nJ per pulse. The phase and amplitude information of the terahertz field can be recovered through electro-optic sampling, enabling the kit to function as a terahertz spectrometer, without further modification.
The kit is preconfigured to provide high performance and reliability. Applications include characterization of nanomaterials, detection of security-sensitive explosives, biomolecular spectroscopy and telecommunications.
