advantest TAS7500TS 太赫The TAS7500TS is a Terahertz (THz) analysis system consisting of an optical fiber laser module and a data acquisition module, which are core parts of our terahertz spectroscopy system (TAS7500SP). Users complete the THz measurement system setup by simply connecting one of Advantest's THz source modules (TAS1110/TAS1130) and a detector module (TAS1230; sources and detectors sold separately). Flexible source selection and source/detector placement allows the user to generate customized experimental The system uses two channels of ultra short pulse lasers (1.55 μm) with either biased output (for THz generation) or signal input (for THz detection). Advantest's unique optical sampling method, utilizing phase-modulated dual-laser-synchronized control technology without a mechanical optical delay line, enables extremely high speed terahertz spectroscopy.SpecificationsSystem configurationDual repetition rate synchronized fiber laser (for THz generation and detection), laser driver, synchronizer, data correction, and analysis PCExcitation LaserCenter wavelength 1550 nmOutput power >20 mW (Option: Max. 50 mW)Pulse width
