The absorption and emission properties of the 4f-5d transition of trivalent praseodymium in fluoride crystals have been characterized, including the CaF2, SrF2, LiYF4 and BaY2F8 hosts. The emission from the 4f5d state to numerous 4f2 levels is observed, and the emission decay time is in the range of 25-29 ns. Attempts to measure gain on the 5d&rarr4f transition have been unsuccessful, as a consequence of an interfering excited state absorption transition due to an electronic transition from the 5d orbital to the conduction band of the host.
