We report on germania and alumina dopant profile shift effects at preparation of compact optical fibers using packaging methods (Stack-and-Draw method, Rod-in-Tube (RiT) technique). The sintering of package hollow volume by viscous flow results in a

For high power fiber lasers, codoping with Al, P or both is necessary to prevent rare earth (RE) clustering in the silica network of the laser active core material. Here, we present a complementary infrared (IR) based multispectral method combined wi

The photosensitivity of various cerium-doped fibers has been experimentally investigated for both excimer- and femtosecond-laser illumination. The results of single-pulse, few-pulse and multi-pulse inscription of fiber-Bragg-gratings with both laser

Fiber Lasers XV: Technology and Systems.
Fiber amplifiers with a robust monolithic seed coupling and very high peak power in a near diffraction-limited beam are increasingly demanded by many industrial applications in laser materials processing. A tapered all-solid rod-type fiber amplifier

At present, the combination of high peak power and near diffraction-limited beam quality is essential for high-power pulsed fiber laser systems combining nanosecond pulses with multi-kilohertz repetition rates. In standard fiber amplifier, parasitic

In this work, a Fabry-Perot optical fiber sensor for the measurement of strain at extreme temperatures is proposed. The cavity is formed by splicing a short section of a silica tube between two sections of single mode fiber. The tube, with a cladding
