Abstract
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 to organic solutions, with no
significant changes in laser-pumping threshold or tuning range.
