description

Upgrade enabling time-resolved pump-probe spectroscopy for cryogenic THz-TDS near-field measurements. The pump laser must be synchronized with the existing THz-TDS spectroscopy and cryogenic near-field systems. The upgrade includes a laser amplifier unit with free-space coupled optical output at 780nm, 100MHz rep rate, pulse energy >1.3nJ, >140mW output power, and customized fiber patch cord for temporal overlap of pump-probe pulses. Additionally, a transmission module enables static pump-probe measurements in transmission, where the sample is pumped via a diffraction-limited beam from the bottom and probed by amplitude- & phase-resolved near-field measurements (pseudo-heterodyne detection) from the top.
