Abstract:
|
The wavelength shift effect of the Whispering Gallery Mode (WGM) laser with
Er3+/Yb3+ co-doped phosphate glass microsphere has been investigated. The experiment was
carried out by half fiber taper coupling technique. The microsphere lasers have been pumped
at 980 nm to take full advantage of energy transfer effect from ion Ytterbium to ion Erbium.
The WGM’s wavelength shift were analyzed for sphere diameters of 90 μm. The observed
lasing lines extends from 1532 nm to 1611 nm. |
