DOI: 10.1364/ol.43.004325
Abstract: In this work, a Tm3+-doped solgel silica microsphere lasing at 2.0 μm is reported. Microspheres with different Tm3+ concentrations are fabricated by overlaying different Tm3+ concentration solgel solutions on the surface of a pure silica microsphere… read more here.
