The USL is part of the Group of Ultrafast Phenomena and Optical Communications at the “Gleb Wataghin” Institute of Physics. Currently, the lab has an 650 square feet space divided in two laboratories. Shortly these labs will move to a new building to a 1200 square feet space, which will allow further development of the experiments. 


Laser Facilities



Amplified Ti:sapphire laser system operating at 1 kHz and 800 nm, delivering pulses of about 80 fs.

Femtosecond OPA covering the range from 400 nm to 2600 nm 





Amplified Yb fiber-based laser system operating at 200 kHz and 1040 nm with pulses of the order of 300 fs.

Three ultrafast NOPAs covering the range from 300 nm to 1600 nm, and delivering pulses as short as 20 fs.





Data Acquisition Facilities



Two-Photon Photoluminescence System 

This home-built two-photon photoluminescence system allows the detection of two-photon excited emission, even from low quantum yield colloidal samples, in the range from 400 nm to 900 nm. 





Time Correlated Single Photon Counting 

This Horiba/Jobin Yvon Nanolog system allows for analysis of the photoluminescence with temporal and spectral resolution. This system operates from 350 nm to 950 nm and covers up to 4 microseconds with a resolution of 25 ps. 

This system is also connected to a visible CCD and a NIR InGaAs array for steady state photoluminescence characterization in a range from 350 nm to 1700 nm.
