Single-polarization cladding-pumped Yb-doped fiber laser

Yb‐doped cladding‐pumped fiber laser with linearlypolarized output emission was realized. To obtain linearpolarization operation we have applied Bragg grating written in the fiber with high birefringence as the input reflector. The polarization extinction ratio was of 17 dB. A maximum output power o...

Description
Summary:Yb‐doped cladding‐pumped fiber laser with linearlypolarized output emission was realized. To obtain linearpolarization operation we have applied Bragg grating written in the fiber with high birefringence as the input reflector. The polarization extinction ratio was of 17 dB. A maximum output power of 12 W was achieved with an efficiency slope of 69%. The laser linewidth was less than 0.1 nm even for maximum output power.
