If the customer is familiar with the principles of THz time-domain spectrometers and has a femto-second laser, the NLS’s Terahertz Time-Domain Spectrometer, T-SPEC, is the best choice. We provide spectrometers for pulse lasers with 780 nm wavelength with the following parameters:
Pulse duration: < 100 fs
Repetition rate: 50 – 100 MHz
Average optical power: 100mW (free space antennas).
The T-SPEC is capable to generate terahertz waves with a bandwidth more than 2.5THz. The THz waves, are generated and detected by photo-conductive antennas. The linear time delay stage and the data acquisition system are controlled using the T-SPEC software package that is included on a USB flash drive or can be installed on a separate laptop.
Applications
