Low linewidth single frequency DFB laser
FBG laser components
Exail’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
ECOC 2020 – December 2020
We report the design and performance of a single frequency all-fibre 2051 nm DFB laser source employing 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…
