We have studied nine laser transitions in Ba vapor at wavelengths
between 1.13 and 3.05 micrometer. Three of these laser lines have not
been reported previously. The relative intensities of the four strongest
transitions (1.13, 1.50, 2.55, and 2.92 micrometer)…

Polymethine laser dyes which fluoresce in the near infrared in
organic solvents generally exhibit poor temporal stability at room
temperature. Two typical laser-pumped polymethine dyes in aqueous
solutions containing nonionic surfactants are investigated. Temporal
stability was improved 20-fold, as compared…

The lasing efficiencies and photochemical stabilities of laser
dyes useful in the 710-1080-nm spectral region have been investigated
using a Q-switched ruby laser pumping source. The measured bleaching
rates P defined as the probability of irreversible decomposition of a dye

The estimation of the heave, pitch, roll, sway, and yaw motions of a DD-963 destroyer is studied, using Kalman filtering
techniques, for application in VTOL aircraft landing.

The governing equations are obtained from hydrodynamic considerations in the form of…
