Time-Domain Terahertz - Toptica

FemtoFiber pro IR / IRShigh-Power Infrared Femtosecond Fiber LasersThe FemtoFiber pro Ir is the base unit of ToPTIcA’s FemtoFiber pro series. Itcomprises a robust, SAM mode-locked oscillator and a power amplifier, andprovides an industry-record average power of > 350 mW. The pulse duration isbelow 100 fs.The short-pulse version FemtoFiber pro IRS features an additional non-linear fiberto generate pulses of less than 40 fs. The pulse width can be controlled by anautomated feedback loop.Both lasers are realized in an alignment-free, polarization-maintaining all-fiber setup,and require neither water nor air cooling. Pulse durations and power levels are wellsuitedfor terahertz generation in organic crystals or InGaAs antennas.Key features· erbium fiber lasers with SAm modelockedoscillator and amplifier· FemtoFiber pro IR:Pulse duration < 100 fs,average power > 350 mW· FemtoFiber pro IRS:Pulse duration < 40 fs,average power > 180 mWSpecifications FemtoFiber pro IR FemtoFiber pro IRSFundamental wavelength 1560 nm 1570 nmLaser output power > 350 mW > 180mWPulse width < 100 fs < 40 fsRepetition rate80 mhz(optional: 40 mhz)80 mhzBeam shape Tem 00M² < 1.2Applications· Terahertz generation in organiccrystals (dAST, dSTmS, oh1)· Terahertz generation in InGaAsphotoconductive switchesBeam divergence < 2 mrad < 1 mradLinear polarization > 95%, horizontal > 95%, verticalOutput couplingFree space88Autocorrelation intensity642Autocorrelation intensity6420-0.6 -0.4 -0.2 0.0 0.2 0.4 0.6Time delay (ps)0-0.8 -0.4 0.0 0.4 0.8Time delay (ps)Autocorrelation pulse width of FemtoFiber pro IR:< 100 fs at 1560 nm.Autocorrelation pulse width of FemtoFiber pro IRS:< 30 fs at 1560 nm.order informationFemtoFiber pro IRFemtoFiber pro IRSM40High-power ultrafast Erbium fiber laser, 1560 nmErbium fiber laser with pulse compression (< 40 fs)repetition rate 40 mhz @ identical average power (only for FemtoFiber pro Ir)
