Journal ArticleDOI
Femtosecond point-by-point inscription of Bragg gratings by drawing a coated fiber through ferrule.
TL;DR: A ferrule-based method of direct fs FBG inscription through protective plastic coating is demonstrated and high-quality FBGs with length from 0.1 to 50 mm are fabricated in polyimide-coated fibers, whose spectra are well described by the theory.
Journal ArticleDOI
Nearly single-mode Raman lasing at 954 nm in a graded-index fiber directly pumped by a multimode laser diode.
TL;DR: High beam quality and narrow spectrum have been obtained in a Raman fiber laser based on a 1.1 km long graded-index fiber directly pumped by a multimode 915 nm laser diode.
Journal ArticleDOI
Durable shape sensor based on FBG array inscribed in polyimide-coated multicore optical fiber
Kirill Bronnikov,Alexey A. Wolf,S. S. Yakushin,Alexandr V. Dostovalov,O. V. Egorova,Sergey Zhuravlev,Sergey L. Semjonov,Stefan Wabnitz,Sergey A. Babin +8 more
TL;DR: It is shown that the sensor allows for reconstructing 2- and 3-dimensional shapes with high accuracy, and the magnitude of the errors of curves reconstruction and errors associated with measurement of curvature radii in the range from 2.6 to 500 mm are investigated.
Journal ArticleDOI
Generating high-quality beam in a multimode LD-pumped all-fiber Raman laser
Ekaterina A. Zlobina,Sergey I. Kablukov,Alexey A. Wolf,Ilya N. Nemov,Alexander V. Dostovalov,V. A. Tyrtyshnyy,D. V. Myasnikov,Sergey A. Babin +7 more
TL;DR: The proposed development and integration of key multimode fiber technologies opens the door to new type of LD-pumped high-power high-beam-quality fiber lasers that may operate at almost any wavelength defined by available LDs.
Journal ArticleDOI
High-speed and crack-free direct-writing of microchannels on glass by an IR femtosecond laser
Evgeny Bulushev,Evgeny Bulushev,V. P. Bessmeltsev,Alexandr V. Dostovalov,Nikolay Goloshevsky,Alexey A. Wolf +5 more
TL;DR: In this paper, the authors investigated high-speed femtosecond laser processing of BK7 glass with the use of design of experiments and regression analysis and obtained an automated inspection technique to extract quality characteristics of test-objects.
