Nufern’s new fibre coverings resist hydrogen gas and high temperatures

Nufern Speciality Optical FibreThe NuSENSOR™ product line, by Nufern, features graded index multimode (MM) fibres designed for Distributed Temperature Sensing (DTS); and single-mode (SM) fibres designed for Distributed Temperature and Strain Sensing (DTSS), and Fiber Bragg Grating (FBG) based sensors.

Both the MM and SM fibres are available with either pure silica or germanium doped core glass compositions, and Nufern is now offering these fibres with carbon/polyimide or carbon/mid-temperature acrylate coatings in addition to the existing polyimide coated fibres. Depending on coating chosen, the fibre is can be protected from temperatures up to 300 °C and H2 rich environments.


Photodigm High Power Single Spatial & Longitudinal Mode Laser Diodes now available in UK

Photodigm is a leading specialist manufacturer of high power single spatial and longitudinal mode laser diodes that deliver unsurpassed performance for applications where beam quality and spectral purity are critical. Elliot Scientific is now offering the Photodigm range to its customers who have requirements for such precision laser diodes in the following fields:

  • Atom Optics
  • Spectroscopy
  • Non-linear Optics
  • Quantum Computing
  • Precision Instrumentation
  • Fibre Amplifiers
  • High-Speed Pulsed Operations

Photodigm manufacture in their own fab so, by controlling all aspects of design and production, their proprietary DBR lasers deliver the highest standards in beam quality and the highest powers available today in individual single mode laser diodes. 

Photodigm DBR lasers are designed to deliver single frequency, single mode laser output. They offer a range of wavelengths and packing options to suit. Full details on our website.

The precisely fabricated ridge waveguide selects a single spatial mode, and the monolithic DBR grating selects a single longitudinal mode. With a narrow bandwidth on the order of 1 MHz, and powers up to 400 mW, Photodigm DBR lasers are uniquely suited to many precision applications and are available in a variety of packages.
