Abstract: Abstract A compound-cavity-based six-wavelength-switchable single-longitudinal-mode (SLM) thulium-doped fiber laser (TDFL) with a homemade polarization-maintaining sampled fiber Bragg grating (PM-SFBG) is proposed and demonstrated. The PM-SFBG in the 2 μm band is studied theoretically and experimentally, and… read more here.

Abstract: We present two kinds of mode-selective-coupler-based ultrafast radially polarized lasers delivering switchable wavelengths and pulsewidths. One is a linear-cavity fiber laser mode locked in the 1.5 µm region, which produces not only wavelength-agile radially polarized… read more here.
