Overview

For distributed feedback single-frequency fiber laser

iXblue’s single-frequency fiber lasers are based on UV Bragg grating technology applied to active rare-earth photosensitive fibers. Ultra short cavity length and phase-shifted design permit ultra-narrow linewidth and robust mode-hop-free laser source properties, ideal for various sensor applications.

1.5 and 2 µm available upon request.

  • 2051 nm narrow linewidth all-fibre dfb laser for holmium-doped fibre-amplifier applications

    D. Traoré, W. Walasik, A Amavigan, R. E. Tench, JM. Delavaux (Cybel); E. Pinsard (iXblue)

    ECOC 2020 – December 2020

    We report the design and performance of a single frequency all-fibre 2051 nm distributed feedback (DFB) laser source employing fibre Bragg gratings (FBGs). Output powers up to 36 mW CW and optical signal-to-noise ratios of > 65 dB/0.05 nm are obtained. Heterodyne measurements yield laser linewidths of ~130 kHz FWHM…
