A switchable and tunable ytterbium-doped fiber ring laser(YDFL) is reported and demonstrated. Employing a Sagnac loop mirror fabricated by an 85-cm-long polarization-maintaining fiber(PMF), the proposed YDFL can opera...
Light-emitting ytterbium-doped tantalum-oxide thin films were prepared using a simple co-sputtering method for the first time. Sharp photoluminescence peaks having a wavelength of around 980 nm were observed from film...

We report a 1 018-nm ytterbium-doped double-clad fiber laser pumped by 970-nm diode. A pair of fiber Bragg gratings with refiectivities of 99.970 and 9% at a center wavelength of 1 018.9 nm are employed as cavity mirr...
A cascaded ytterbium-doped all-fiber master oscillator power amplifier(MOPA) with 1064-nm pulsed laser is demonstrated,and it can produce up to 20-W average power and 0.1-mJ pulse energy at tunable repetition rates ...
We report on hundred watts range ytterbium-doped all-fiber laser assembly based on the master oscillator power amplifier structure. It consisted of an oscillator and an amplifier with all-fiber components. And fiber f...
