In this paper, we present the demonstration of a 10-W level picosecond Yb 3+ -doped master oscillator and power amplifier at 976 nm in all-fiber configuration. A linear-cavity Yb 3+ -doped fiber la…
Single-frequency distributed Bragg reflector fiber laser at 915 nm was demonstrated by using a 2.5-cm long Nd 3+ -doped phosphate fiber as the gain medium. An output power of 13.5 mW was obtained a…
The spectroscopic properties of Er 3+ -doped tellurite glasses were investigated and a 1 wt.% Er 3+ -doped tellurite fiber was fabricated for L-band lasers. Wavelength-tunable fiber lasers in a lin…
