Dual-beam laser - photoelectric spectrometer
Light source: two Opolette 355 lasers with an Nd:YAG pump equipped with optical parametric oscillators (OPO) tunable in the range of 210-2400 nm with a peak pulse power of 500 kW.
Detection system: Zahner-Elektric IM6 electrochemical workstation with fast data acquisition system (TR8M)
Control system: precise synchronization system (Photon Institute).
The spectrometer will allow for a detailed analysis of the dynamics of carriers generated in semiconductor structures, examination of the properties of trap states and research on the mechanisms of short-term memory effects in the so-called photoelectrochemical synapses. Additionally, the device enables measurements using photomodulation spectroscopy (CIMPS).
