Helical Bragg gratings: experimental verification of light orbital angular momentum conversion
A. G. Okhrimchuk, V. V. Likhov, S. A. Vasiliev +1
Structured light, in particular light possessing orbital angular momentum (OAM), has been actively studied in recent decades. Helical Bragg grating (HBG) is a reflecting optical el…

2.1 um CW Raman Laser in GeO2 Fiber
B. A. Cumberland, S. V. Popov, J. R. Taylor +3
We report on 33 % efficient generation of the first Stokes in a high concentration GeO2 fiber Raman laser pumped by a 22 W Thulium doped fiber laser. An output power of 4.6 W at 2.…
