We demonstrated lutetium oxide (Lu2O3) deposited onto D-shaped fiber producing Q-switched ytterbium-doped fiber laser (YDFL) with an operating wavelength of 1037 nm. D-shaped fiber Lu2O3 as a saturable absorber (SA) was prepared using a polishing-wheel technique by polishing 2 times to establish an...
