PROJECT TITLE :
Femtosecond Laser Inscription of Long-Period Fiber Gratings in a Polarization-Maintaining Fiber
The strategy of femtosecond laser inscription by slit-apertured beam is applied for fabrication of long-period fiber gratings in polarization-maintaining Panda-type fiber. Polarization properties furthermore ambient refractive index sensitivity are investigated for the inscribed gratings. It is shown that the strategy allows us to make high-quality element for the utilization as spectral filter of high-power fiber laser furthermore high-temperature sensor.
