Newport has introduced the terahertz (THz) pulse-generation kit using a sub-35-fs Ti:sapphire amplifier system.
The kit can be easily integrated with a Ti:sapphire amplifier to generate terahertz pulses, which can be further used for linear, nonlinear and time-resolved spectroscopy applications.
The THz pulse-generation kit utilises standard Newport optics, opto-mechanics, manual stages and Conex-based motorised solutions to provide high performance and accuracy.
The 800nm Ti:sapphire laser pulse (1kHz ~300uJ per pulse) is focused into ambient air to generate the air plasma that produces THz pulses.
With this design, the damage threshold is not a concern as the air replenishes itself from pulse to pulse.
The generated THz pulse has the oscillation that spans about 1ps and has the estimated pulse energy of 0.1-0.3nJ per pulse.
Furthermore, the ability to recover the phase and the amplitude information of the THz field through electro-optic sampling enables the kit to function as aTHz spectrometer, without further modification.
