Brillouin HyperFine Spectrometerwith “GREEN KILLER” pump suppression HF-8999-532
Massive Dynamic Range, Ultra-Fast Acquisi9on, MHz precision, User-friendly
The great challenge with Brillouin spectroscopy is that the Rayleigh light from the pump laser canoverwhelm the small Brillouin shi8ed return signal. So, we have combined our leading edge
HyperFine spectrometer with a very narrow band tunable ﬁlter to suppress the bright un-shi8ed
laser frequency. The tunable ﬁlter (the Green Killer) is easily adjusted to suppress the main laser
peak and exposure gaJng is used by the HyperFine spectrometer to drasJcally increase the fulldynamic range of the instrument. This combinaJon achieves a dynamic raJo of 75 db with ourultra low noise sCMOS camera.
The tunable ﬁlter is comprised of a double passed air spaced etalon. LightMachinery’s proprietary ﬂuid
jet polishing process is uJlized to create both the tunable etalon ﬁlter and the main VIPA etalon in thespectrometer. Together, these high ﬁnesse elements provide unparalleled sensiJvity in a relaJvely
compact size, perfect for Brillouin scaXering.
