Generation of dissipative and conventional solitons in a single $2\ \mu \mathrm{m}$ fiber laser

Both conventional solitons (CS) and dissipative solitons (DS) are generated in a
$\boldsymbol{2 \mu \mathrm{m}}$
fiber ring laser cavity. By adjusting the intracavity polarization controller positions and modifying the pump power, switching between different types of ultrashort pulse generation is demonstrated.
