ABSTRACT: The only fluorite doped with Nd previously found to ex-.'_--1'_
hibit stimulated emission at room temperature was SrF (L. F. Jchn-

crystals grown from the malt in a fluoriding atmosphere by lcwring
the crucible. Emission was observed in crystals with neodymium
oxide concentrations 0.3 and l.S%
.o the approximate wavelengthbeing
1.047 micron. The system was excited by, absorption of light from a
-21
flash system at 14,000 cm above ground level. Emission correspond-
ed to the 4F 41 transition. The illuminating system con-
3/2 11/2
sisted of an elliptical system with the crystal in one focus and the
flash lamp (80-mm glow column) in the othek. The time dependence
of the radiation was determined with a photomultiplier and os(,.,illo-
$1 scope* The structure of the radiation was determined with a apec-
trograph having a 600 line/mm grating. For the crystal with 0.3%
neodymium oxide the emission line width was.approximately 3 1 (4
fine structure componentaL increasing to S A (12 components) Eor the
1.5% crystal. "The authors are grateful to V. V. Osiko and Yu. K.

Crystals 150 mm 'long with a 15-mm dianieter were grown from the same melt under
identical conditions and had the same concentration of active iMDurities. Thirteen
laser rrAs, each about T3 mm long and 6.5 mm in diameter, -were fairicated from the crysr
tals. Measurements of the excitation threshold, the gradient of the index of refrac"
tipn, the local 46homogefieities, and small angle scattering showed that ttte optical de -

cedure deecribed earlier (FN v. T,j 26T.Jo 19r,09 Thai absorption spectra were obtained
with a diffractioA spectrometer. In all cryfitals, Jxradiation greatly reduced the
intensiti6s. of lines and gave rise to new lines. 'From a. comDari-
soil of Ahe absorption coefficients at the line mxivia before and after irradiation
it is easily seen,that: 1) the lines comprIsing a single system are decreased in
like f"bionp and ~ 2 ) the decrease to'strorggest in rhombic-symmetry lines and prac-

ABSTRACT: Preliminary data are given on the operation of a CaF2;Nd3+ laser with a
wide-angle beam divergence in the 50-400K range (see Table 1). The test crystals
were synthesized by means of a method described elsewhere (A. A. Kaminskiy, L. S.
Korniyenko, and A. M. Prokhorov,.ZhETF, v. 48, 1965, 476). The specimens were
approximately 75 mm long and 6.5 mm in diameter and bad highly polished sides. Two
groups of crystals were studied: 1) those with poor end parallelism (1-5) and those
with improved optical quality (6-10). The cavity in all cases consisted of 13-layer
dielectric mirrors coated on the'rod ends. Transmittivity was approximately 0.7%.at
1.06 U. Excitation at low temperatures was done by means of an elliptic cylinder'
reflector with an IFP-800 xenon lamp with an efficiency of about 15%. At 300K a
similar but more efficient (50%) pumping source was used. The spectral composition
of axial and extra-axial emission was recorded by means of a DFS-13 diffraction
