We report stabilization of a thulium-holmium codoped fiber soliton laser with a saturable absorber based on carbon nanotubes. The laser generates transform-limited 750-fs pulses with 0.5-nJ energy.

In this paper, the carbon-fiber-wrapped rotor strength for High-speed permanent magnet synchronous machine (HSPMSM) was studied. Firstly, considering the carbon fiber wrapping process, the carbon ...
