Abstract: The photostability of five coumarin dyes was studied on exposure to an XeCl* laser. Basic and fluorescent additives were used to improve the photostability. It was established that the former enhanced the service life of coumarin derivatives by a factor of 5–7 while the latter are best used to maintain the lasing efficiency during the initial period.
