Continuous-wave ultraviolet laser action in strongly scattering Nd-doped alumina.

چکیده
We report electrically pumped, cw laser action near 405 nm from Nd(3+) -doped delta -alumina nanopowders. To our knowledge, this is the first report of stimulated emission from the high-lying F(2) -excited states, achieved through feedback from strong elastic scattering of light over transport path lengths shorter than half a wavelength.

Laser action in strongly scattering rare-earth-metal-doped dielectric nanophosphors
We report continuous-wave laser action in two oxide nanopowders doped with Ce and Pr ions. To our knowledge, these are the first observations of stimulated emission from electrically pumped random media in which scattering and distributed feedback scale lengths are much shorter than a wavelength. The continuous nature of the laser emission in small volumes ~on the order of a cubic wavelength! o...
متن کاملContinuous-wave diode-pumped laser action of Nd³⁺-doped photo-thermo-refractive glass.
Laser action of the photo-thermo-refractive (PTR) glass, which is the photosensitive material for holographic recording of volume Bragg gratings (VBGs), was demonstrated for the first time by introducing Nd³⁺. Nd:PTR glass has a bandwidth of 27.8 nm and 16.0 nm for luminescence and absorption, respectively. An uncoated 2 mm thick Nd:PTR element generated cw laser output of 124 mW, with a slope ...

متن کاملContinuous-wave Lasers in Polymer waveguides
Channel waveguides based on a polymer, 6fluorinated-dianhydride/epoxy, which is actively doped with a rare-earth-ion-doped complex, Nd(thenoyltrifluoroacetone)3 1,10-phenanthroline, have been fabricated. Photoluminescence peaks at 880 nm, 1060 nm, and 1330 nm have been experimentally observed. By optimization of the fabrication procedure of both, host material and optical structure, continuous-...
متن کاملMulti-wavelength emission through self-induced second-order wave-mixing processes from a Nd3+ doped crystalline powder random laser
Random lasers (RLs) based on neodymium ions (Nd(3+)) doped crystalline powders rely on multiple light scattering to sustain laser oscillation. Although Stokes and anti-Stokes Nd(3+) RLs have been demonstrated, the optical gain obtained up to now was possibly not large enough to produce self-frequency conversion. Here we demonstrate self-frequency upconversion from Nd(3+) doped YAl3(BO3)4 monocr...
