Streak Cameras Installation

New Streak Camera System has been installed and is running

Two new Streak camera systems from Hamamatsu were recently installed in our labs. One camera covers the entire visible region with an outstanding 1.35ps temporal resolution, while the second system covers, in addition, the near-infrared spectral range down to 1600nm. With these systems, we can simultaneously measure photoluminescence spectra across a broad spectral range and lifetimes over a wide dynamics range from picoseconds to microseconds. 


The femtosecond pulses required for sample excitation are provided by a full wavelength tunable Optical Parametric Oscillator (OPO) from Radiantis pumped by a Spectra Physics MaiTai oscillator. Two pulse pickers (PulseSelect from A.P.E.) allow us to control the repetition rate over a wide frequency range from 80 MHz down to several kHz.
