Time-Domain Terahertz - Toptica

High Power ExtensionLaser Amplifier with Fiber Input / OutputThe High Power Extension is the recommended tool for researchers who need extralaser photons to drive large-area terahertz emitters or to compensate for power losses inadditional modules (e.g., Phase Modulation Extension, or fiber taps).At 850 nm, the package comprises a BoosTA semiconductor amplifier with a fiber inputport and a 50:50 % fiber-splitter on the output side. The BoosTA amplifies the two-coloroutput of the Standard Package to more than 300 mW, while avoiding any cross-talkbetween the two lines. All of the spectral properties of the Standard Package remainunchanged.A 1550 nm version of the High Power Extension is also available, employing an Erbiumdopedfiber as gain medium.Key features· BoosTA: Semiconductor amplifierwith two SM/PM fiber outputs· 150 mW per output, @ 850 nm·1550 nm Erbium fiber amplifieravailable on requestSpecifications THz High Power / 850 THz High Power / 1550AmplifierWavelengthSemiconductor amplifier(BoosTA 850 L)853 + 855 nm, definedby Standard Package**Erbium fiber amplifier*Range 1535 .. 1565 nm,defined by TeraBeamApplications· Laser source for large-area terahertzemitters or emitter arrays· Recommended for systems withPhase Modulation ExtensionDifference frequency tuningDifference frequency resolutionFiber output powerCf.
