Metrology Laboratory No. II

Summary:

In this laboratory, studies of the nonlinear optical properties of various organic materials are performed (bulk and in nanostructures); these materials find applications mainly in the area of photonics and biophotonics. Photophysical processes such as photoluminescence, energy transfer, quantum efficiencies, among others, are also studied. The propagation of short pulses in different media and their characterization (duration, form and phase) is also studied.

Techniques:

Two-photon excited fluorescence (TPEFs), TCSPC, integrating sphere for quantum yield measurements, Z-scan, SHG-FROG, short pulses compression, THG-maker Fringes, acquisition and processing of images for luminescent biological specimens.

Equipment:

Femtosecond láser (Ti:Sa, 80 fs, 1 Watt, sintonizable 730 – 840 nm), Spectra Physics, Model 3941; Nd-YVO4 CW laser (532 nm, 6 Watts), Spectra Physics, model Millenia VI, Holographic Table 2.40x1.40 m, Fluorometer from Edimburg Instruments, model FS5; TCSPC module, integrating sphere; power meter; oscilloscope.
