SFG Spectrometer
OVERVIEW
Sum Frequency Generation (SFG) Spectrometer by EKSPLA.
Vibrational Sum frequency Generation (VSFG) spectroscopy is powerful and versatile method for in-situ investigation of surfaces and interfaces. in VSHG experiment a pulsed tunable infrared iR (ωIR) laser beam is mixed with a visible VIS (ωVIS) beam to produce an output at the sum frequency (ωSFG = ωIR + ωVIS). SFG is second order nonlinear process, which is allowed only in media without inversion symmetry. At surfaces or interfaces inversion symmetry is necessarily broken, that makes SFG highly surface specific.
SPECIFICATION
- Rep Rate Range: <1 kHz
- Pulse Duration: 20 ps
Applications
- Investigation of surfaces and interfaces of solids, liquids, polymers, biological membranes and other systems
- Studies of surface structure, chemical composition and molecular orientation
- Remote sensing in hostile environment
- Investigation of surface reactions under real atmosphere, catalysis, surface dynamics
- Studies of epitaxial growth, electrochemistry, material and environmental problems
