Q-switched and mode-locked fibre lasers have been successfully demonstrated in ytterbium-doped fibre laser cavity by taking an advantage of the optical absorption of antimony telluride (Sb 2 Te 3 ) material. The Sb 2 Te 3 was embedded into polyvinyl alcohol to function as a saturable absorber (SA)....
