Introduction:

The high-pressure ultrafast pump-probe system can achieve on-site in-situ pressuring. The setup can perform pressure tuning and calibration under 70 GPa, and ultrahigh-pressure (> 100 GPa) temperature-dependent experiments

Introduction:

The light-source of time-resolved pump-probe ultrafast spectroscopy system, consisted of Regenerative Amplifier, Oscillator, and Broadening Compressor. The femtosecond pulse laser has a repetition rate of 250 kHz (i.e., laser pulses are emitted every 4 μs), a central wavelength of 800 nm, and a pulse duration of 70 fs.

Introduction:

Transfer 800 nm femtosecond laser beam into femtosecond laser beam with tunable central wavelength (500-2400 nm).

Introduction:

The iHR550 imaging spectrometer is suitable for Raman, fluorescence, photoluminescence, absorbance/transmission/reflection/emission analysis and other experiments. The focal length is 550 nm and the maximum grating line number is 2400.

Introduction:

The THz time-domain spectroscopy device uses the GaAs antenna grown at low temperature as the THz emitter and detector. It can realize the such functions: the transmitted and reflected THz time-domain spectroscopy, 800 nm femtosecond laser pump-transmitted and reflected THz probe ultrafast spectroscopy and THz emission spectroscopy.

Introduction:

This laser was set in cooperation with L07 Group, Optics Laboratory, IOP, CAS. It can generate 10 fs ultrashort pulses by introducing CW light, and provide ultra-high time resolution when combined with other devices.

Introduction:

Split pair superconducting magnets provide an experimental platform for variable field orientation and field strength (standard maximum 7 T) for ultrafast spectral measurement. There is no liquid helium in the beam path, and it has active shielding to minimise stray field footprint. The homogenity of magnetic field (over 10 mm DSV) is 0.5%; the split angle is ± 2°; the sample temperature range is 1.6-300K.

Introduction:

The Smart Raman microconfocal module enables high-resolution Raman spectroscopy and wide-range photoluminescence spectroscopy.
