Integrated 808 nm wavelength SLDs with a ring SLD seed source and a tapered amplifier were fabricated. Output power of 400 mW was obtained in continuous wave (CW) mode at room temperature. The full width at half maximum (FWHM) of the emission spectrum is 31 nm.
A high-power and high-speed laser source was studied in this paper. The laser source consists of a high-speed DFB laser diode modulated by a LiNbO3 modulator and a two-stage hybrid fiber amplifier. The hybrid fiber amplifier contained a C-band erbium doped fiber amplifier pumped by a single mode laser diode, and an erbium/ytterbium co-doped double-cladding fiber amplifier pumped by two multimode laser...
