LightMachinery Inc.The great challenge with Brillouin spectroscopy is that the scattered signal from the un-shifted wavelength of the laser can overwhelm the small Brillouin shifted return signal. LightMachinery has combined its leading-edge HyperFine spectrometer with a very narrow band tunable filter to suppress the bright un-shifted laser frequency.
PhotonTec Berlin GmbHPhotonTec Berlin expands its wavelength stabilized diode family with a new high-brightness 976 nm diode of 140 W power from a 105 µm core and 0.22NA fiber pigtail. Utilizing volume grating, the emitting wavelength is stabilized at 976 nm and insensitive to operating temperature and current.
