TeraScan 850 / 1550ToPSellers for Frequency-domain SpectroscopyKey features· Preconfigured systems with high-endGaAs or InGaAs photomixers· highest bandwidth and best dynamicrange: TeraScan 850· most compact and inexpensivespectroscopy platform: TeraScan1550TOPTICA’s TeraScan systems are “TOPSeller” configurations, designed for some of the mostcommon frequency-domain terahertz applications. The TeraScan 850 consists of StandardPackage 850 + Basic Spectroscopy extension 850. Based on GaAs photomixer technology, itoffers an outstanding bandwidth and maximum dynamic range. The TeraScan 1550 unites theTeraBeam laser and the InGaAs terahertz emitters/receivers of the Basic Spectroscopy extension1550. This assembly provides the most compact solution for cw terahertz spectroscopy. Bothsystems feature an intuitive software interface and ToPTIcA’s proprietary Teracontrol module forcomputerized frequency tuning and terahertz data acquisition.Applications· Well-established starter package forcw terahertz spectroscopy· Base unit for system integratorsSpecifications TeraScan 850 TeraScan 1550ComponentsLasersStandard Package 850& Basic Spectroscopyextension 8502 x dL dFB To3TeraBeam 1550& Basic Spectroscopyextension 1550TeraBeam, including2 butterfly-packaged DFBdiodesWavelength 853 + 855 nm 1546 + 1550 nmTerahertz emitter GaAs photomixer InGaAs photodiodeTerahertz receiver GaAs photomixer InGaAs photomixerAntenna type Log-spiral Bow-tieAntenna packagecylindrical, Ø 1”,SM/PM fiber pigtailcylindrical, Ø 30 mm,SM/PM fiber pigtailTerahertz power (typ.)2 μW @ 100 Ghz0.3 μW @ 500 Ghz4 μW @ 100 Ghz0.5 μW @ 500 GhzDFB laser #1AC Bias~TXTerahertz dynamicrange (@ 300 ms lock-intime)80 dB @ 100 Ghz70 dB @ 500 Ghz70 dB @ 100 Ghz50 dB @ 500 GhzTHz scan range Typ. 0 – 1800 Ghz Typ. 0 – 1200 GhzTuning speedup to 100 Ghz/sDFB laser #2Lock-inDetectionRXFrequency accuracyFrequency control2 Ghz absolute< 10 mhz relativeexternal Pc + Teracontrol Tc 110 (included)TOPTICA’s TeraScan systemsconsist of Standard Package (green)and Basic Spectroscopy Extension(bright yellow).order informationTeraScan 850TeraScan 1550Two-color dFB laser, 853 + 855 nm, with driver electronics,FPGA-based frequency control, and two GaAs photomixerscompact two-color dFB laser (TeraBeam 1550), with driver electronics,FPGA-based frequency control, and two InGaAs photomixers26 | www.toptica.com
