The Centre Laser Infrarouge d'Orsay (CLIO) houses OPO IR lasers (nanosecond or picosecond) and a free electron laser (LEL) tunable in the infrared. Only two other LELs, one based at the University of Nijmegen (The Netherlands), the other at the Fritz Haber Institute in Berlin (Germany), are also easily and rapidly tunable in a wide infrared range (4-100 microns), and deliver 40-80 microJ picopulse trains.
These IR sources are permanently coupled to tandem mass spectrometers to characterize ions via IR-induced fragmentation (IRMPD). IR lasers are also used for SFG interface spectroscopy and spectromicroscopy ("AFMIR").
