Laser Mira HP (Sincrotrone Trieste)
The X-ray absorption spectroscopy (XAS and XMCD) open up various opportunities to probe laser-induced changes of the electronic, magnetic and geometric structure. The properties of the TR-XAS/XMCD@BACH endstation offer wide experimental conditions with respect to repetition rate, overall energy range, time-resolution, operation modes of the Synchrotron source and sample experimental enviroments.
Elettra Synchrotron radiation source provide radiation pulse widths sufficiently short to investigate dynamic processes in the time between 70 ps up to 0.5 μs. Typically, optical excitation of the sample is done by laser pulses (synchronized to either hybrid or multi bunch SR pulses), and probing is performed by time-delayed synchrotron radiation pulses. For the optical excitation of the sample we use a Mira HP Ti:Sa oscillator with a pulsepicker and produces nJ pulses with a repetition rate tunable between 0.01 and 83.3 MHz.
