Measurements of device parameters for Nd:YAlO3lasers

This paper presents measurements of several properties of Nd:YAlO
3
useful in the design of laser devices. Values for the gains, cross sections, and saturation parameter of the
4F_{3/2} \rightarrow 4I_{11/2}
transitions are presented for principal axis polarizations. Thermal focal lengths, spherical aberration, and astigmatism for
A-, B-
, and
C
-axis rods
\frac{1}{4}
in in diameter and 3 in long are shown as a function of input power. Pumping efficiencies with krypton and xenon lamps are compared for Nd:YAG, Nd:Cr:YAlO
3
, and Nd: YAlO
3
both in the CW and flash-pumped modes. Finally, the effects of varying the Nd concentration in YAlO
3
from 0.4 to 1.15 percent are discussed.
