Facilities

Overview

A panomatic view of our laboratory: room B116 in Biomed Phys Sci Bldg.

The laboratory is currently equipped with a 10 Tesla superconducting magnet (Oxford Instruments Spectromag SM4000) with a top-loading Helium-3 refrigerator (HelioxTL, down to ~300 mK); a liquid helium flow optical cryostat for low temperature optical measurements down to ~2 K; a Ti:Sapphire pulsed laser oscillator (Mira 900D) and a synchronously pumped optical parametric oscillator running at 76MHz (covering a wide wavelength from λ=550 nm to ~ 3300 nm in ps or 100fs mode), and a pulse picker to select pulses with repetition rate ~1kHz to 4MHz; a liquid crystal spatial light modulator (Holoeye PLUTO-NIR2) for laser pulse and beam shaping; a liquid crystal polarization control system (Meadowlark) for automatic polarimetry measurements; a streak camera system with 2-ps time resolution for time-resolved spectroscopy and polarimetry; a photon counting system (Picoquant PicoHarp 300 and two MPD detectors) for Hanbury Brown-Twiss type measurements; two spectrometer systems for VIS-NIR (λ~ 400nm-1000nm) and IR (λ~900nm-5000nm) equipped with liquid nitrogen cooled Si- and InGaAs CCDs, and a PbS solid-state detector with a lock-in amplifier for high spectral resolution spectroscopy.
