We have demonstrated an 1180-nm linearly-polarized single cavity fibre laser with an output power of 10.8 W using an Yb-doped polarization-maintaining solid photonic bandgap fibre. A slope efficiency of 56% has been achieved.
We have demonstrated an output power of 5.6 W at 1180 nm in linearly-polarized fiber laser using a low-loss ytterbium-doped polarization maintaining solid photonic bandgap fiber. A slope efficiency of 31 % has been achieved.
A low loss ytterbium-doped polarization maintaining solid photonic bandgap fiber (SPBGF) is fabricated using a new fabrication method. A high efficient fiber laser operated at the low-gain wavelengths is prospected by the fiber.
A low splice loss solid photonic bandgap fibre (PBGF) is realized by deploying a depressed clad layer. The temperature dependence of the filtering wavelength of the PBGF is measured.
Bend sensitive wavelength filtering property in a concentric core solid photonic bandgap fibre is resented. The property is realised by not only the bandgap effect but mode coupling between the core mode and ring modes.
We demonstrate suppression of amplified spontaneous emission at 1030 nm in a cladding-pumped ytterbium-doped solid photonic bandgap fiber. This fiber should play an important role for a high power fiber laser lasing around 1180 nm.
We demonstrate a wide-band and low-loss (< 4 dB/km at 1520 nm) solid photonic band-gap fiber (PBGF). The fiber is practically single-mode in a long length regime and has a large anomalous dispersion over a wide wavelength range.
We propose a single-mode photonic band-gap fiber with an extended triangular lattice cladding and a capillary core. We numerically optimize the design of the core and show that the fiber has a very wide transmission window, such as from 1200 nm to 2300 nm
