By adding 14 mol % P(2)O(5) to the core of a SiO(2):Nd fiber, laser emission was obtained at 1.36 microm. From the fluorescent spectra and laser thresholds for the (4)F(3/2) to (4)I(11/2) and (4)F(3/2) to (4)I(13/2) transitions, the net gain at 1.36

The stoichiometry of the layered metallic scandium iodide Sc{sub 0.93}I{sub 2}, reported earlier is confirmed. The compound was prepared by the reaction of ScI{sub 3} with excess metal over a sizeable temperature range; however, the composition was n

A new class of solid-state tunable lasers based on Cr3+in low ligand field materials is described. Spectroscopic and calculated laser properties have been obtained for the4T 2 emission in two low field crystals: K 2 NaSc 1-x Cr x F 6 and Al 1-x Cr x

Absorption spectra of ${\mathrm{Cr}}^{3+}$-doped glasses exhibit features which are interpreted as Fano antiresonances resulting from interaction of $^{2}E$ and $^{2}T_{1}$ states with a vibrationally broadened $^{4}T_{2}$. Inhomogeneous line broaden

Photoemission spectroscopy has been used to investigate the valence band of Cd${\mathrm{Cr}}_{2}$${\mathrm{Se}}_{4}$ and Cd${\mathrm{Cr}}_{2}$${\mathrm{S}}_{4}$. The occupied $d$ bands for both materials have been found to lie below the top of the va

The earlier glass lasers in both rod and fiber form were mostly side pumped.1 With the demonstration of single mode CW fiber lasers doped with Nd in low loss glass2 there followed considerable work with end pumped fiber lasers with many of the rare e
The objectives of the research involved preparation of a number of Cr/sup 3 +/ doped glasses beginning with common commercial types, and expansion of the number and variety of glasses as time allowed. The Cr/sup 3 +/ doped glasses have been evaluated

The first erbium glass lasers at 1.54μm were made from alkali, alkaline earth silicates with ytterbium added as a sensitizer.1 They were used primarily as Q-switched oscillators for eye safe range finders.2,3 With the demonstration of CW fiber laser
