Notice Title
sSNOM Upgrade for University of Manchester
Notice 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.

Software Development Kit for neaSCAN 4. THz Pump-Probe operation * additional delay line & synchronized software control for pump probe * amplifier unit with free-space coupled optical output at 780nm with amplifier unit mounted on optical table next to neaSNOM microscope * 100MHz rep rate, pulse energy >1.3nJ, >140mW output power * Customized fiber patch cord for temporal overlap of pump-probe pulses
Procurement Information
Attocube systems AG is the only company worldwide, who manufactures a scattering-type near-field optical microscope (our pre-upgrade system) that enables simultaneous background-free imaging and spectroscopy on nanometre length scales in the visible-IR-THz range. Their exclusive design works with the following patents: * Patented parabolic mirror design for focusing and collection of light * Patented dual-port design to allow two beams of light to be focused on the atomic force microscope (AFM) tip for nanoscale imaging and spectroscopy * Patented signal processing for optical background suppression * Patented pseudo-heterodyne detection (PsHet) technology for background suppression * Patented interferometric design (nano-FTIR) for background-free optical detection technology and simultaneous detection of optical amplitude and phase and hyperspectral imaging * Patented high speed holography for multispectral imaging * Patented phase shifting detection to extract relative phase These patents and the exclusive design have enabled the neaSCOPE system to conduct amplitude and phase-resolved vector field, reflection, and absorption mapping with nanoscale spatial resolution. It is currently the only solution provider on the market that enables dual-port s-SNOM operation combined with a high NA parabolic mirror, which is essential for low SNR THz TDS and pump-probe measurements. In particular, attocube systems AG is the only company who can upgrade the existing cryogenic s-SNOM system (cryo-neaSCOPE) based at University of Manchester to perform nanoscale THz-TDS and pump-probe imaging and spectroscopy at low temperature. Therefore, the same manufacture of the pre-upgraded s-SNOM system is required to ensure: * All upgrade subsystems must be compatible with the existing microscope controls (both in hardware and software), while still being amplitude- & phase-resolved and background-free. * Pump laser must be electronically synchronized with the existing cryogenic THz-TDS spectroscopy system * Excitation wavelength must be compatible with optical windows in the cold shroud of the existing cryo-neaSCOPE system
