Laboratory of optical spintronics
The primary purpose of the Laboratory of optical spintronics, which was estalished in 2011, is to study ultrafast spintronic phenomena in solids using magneto-optical time- and spatially-resolved spectroscopy. The experimental setup allows for measurements in magnetic fields and a wide range of temperatures in the transmission and reflection geometries.
The laboratory is a part of the Laboratory of OptoSpintronics, a joint facility of the Faculty of Mathematics and Physics, Charles University and the Institute of Physics of the Academy of Sciences of the Czech Republic.
Laboratory equipment
The core of the laboratory consists of a pump-probe setup with a spatial resolution. Key equipment includes:
- femtosecond Ti:sapphire laser Mai Tai HP, Spectra Physics (pulse energy 30 nJ, wavelength tunability 690-1040 nm, 120 fs, repetition rate 82 MHz)
- Inspire HF optical parametric amplifier, Spectra Physics (wavelength tunability 350-2200 nm)
- pulse picker
- continuous Ti:sapphire laser 3900S, Spectra Physics (wavelength tunability 700-1000 nm)
- closed-cycle He cryostat by Advanced Research Systems (temperature range 10-800 K, vibration < 1 nm, electrical connectors)
- Walker Scientific electromagnet (up to 1.5 T)
- focusing system for optical beams down to ~1 μm diameter
- arrangement for magneto-optical microscopy
