EXFO’s new CW tunable laser offers 10 pm resolution and 100 kHz linewidth in the C or L bands

FLS-2800-1HRThe EXFO FLS-2800 is a continuous wave (CW) tunable laser with a high-power output, narrow 100 kHz linewidth and 10 pm resolution tunability over the C or L band. This laser offers a cost-effective and versatile solution for various applications, including coherent/orthogonal frequency-division multiplexing (OFDM) transmission and WDM network emulation. The FLS-2800 is available in single- or dual-laser configurations.

The FLS-2800 is easy to directly control using the knob on the front panel. Each laser is controlled separately, and both wavelength and power can be adjusted quickly and precisely. It is also possible to view the status of and control the FLS-2800 remotely via the USB or Ethernet ports by means of EXFO’s TLM user interface.

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.

New Sprite-t and Firefly-THz Lasers from M Squared



As part of their continuous product improvement program, M Squared have released new versions of their Sprite-t and Firefly-THz lasers. The improvements go deeper than the redesigned skins, with numerous tweaks to both lasers:

  • Sprite-t now incorporates PowerMax™ active pump beam alignment and also has reduced  power requirements.
  • Firefly-THz has an improved tuning range, offering 0.8 to more than 2.5 GHz, plus output pulse energies now in excess of 9 nJ.

BPF Series THz and IR Band Pass Filters from Lake Shore

Lake Shore’s BPF Series band pass filters are specifically designed for applications where precision and dependability are paramount, especially when used in extreme environments. Over 100 standard models include four common aperture sizes and over 25 center wavelengths (CWLs) spanning from 10 to 590 µm (about 500 GHz to 30 THz), making these filters readily available to researchers who want to avoid custom engineering charges and get on with their work without delay.

Features and capabilities

  • Precision frequency selective surfaces (FSS) for high spectral resolution
  • Narrow pass bands with excellent transmission
  • Pure gold filter element for best results in thermal cycling and gamma radiation conditions
  • Designed for use in cryostats and adjacent to cooled detectors
  • Compact and lightweight
  • Superior performance with “stacked” configurations
  • Temperature stable and radiation tolerant
  • Three year warranty
