Wavelength tunable laser operation has been obtained from the solid-state crystal alexandrite (BeAl 2 O 4 :Cr3+) over the continuous range from 701 to 818 nm. The tunable emission was observed at room temperature and above in a homogeneously broadene

Accurate measurements of the x-ray lattice constant of a pure argon crystal yield an x-ray density of ρ x =[1.74974 + (4.349 × 10−4 deg−1)T—(2.338 × 10−5 deg−2)T 2] g cm−3 in the temperature interval 60 to 83°K, with an r.m.s. deviati

Diffraction studies were carried out near 4°K on the influence of rate and method of growth upon the perfection and microstructure of 99.998% purity argon crystals. The crystallography of the twinning observed was directly verified to be of the type

This paper describes the results of an investigation of the interrelated physical parameters that determine laser threshold for three organic dyes: rhodamine B, rhodamine 6G, and fluorescein. Not only are these dyes (rhodamine 6G in particular) among

Crystals of 99.998% purity argon were prepared by directional solidification of the liquid. The x-ray lattice constant was measured by means of a rotating-camera method, and the volume coefficient of thermal expansion was determined over the range 2.

Laser emission is reported from flashlamp‐excited polymethyl methacrylate rods containing rhodamine dyes. Quenching of stimulated emission by the molecular triplet state is apparently reduced in the solid with respect to that observed for the same
