Abstract
Amplified spontaneous emission broadband light around 2?m has been successfully generated in both double-clad Tm-silica and Tm:Ho fluoride fibres using a high-power 803?nm diode laser pump source. For the Tm-silica fibre an output power was produced greater than 40?mW and with a bandwidth (full width at half-maximum (FWHM)) of about 50?nm. For output powers greater than 90?mW, the FWHM of the output spectrum reduced to about 40?nm. The Tm:Ho fluoride fibre source produced about 2?mW output power and an FWHM of about 20?nm; this was reduced to about 10?nm as the output power was scaled up to 20?mW. The central wavelength for each system was greater than 2?m.
