Abstract :
Photodarkening and photobleaching of Yb-doped germanosilicate and aluminosilicate fibers have been studied. We show violet laser diodes (407nm) can efficiently bleach photodarkening even with low-intensity cladding-irradiation. Coirradiation of pumping and bleaching lights was also investigated.
