Abstract :
We report the first demonstration of laser emission from the 3F3 to 3F2 transition in the rare earth praseodymium. This new 7-μm solid-state laser operates with an optical efficiency of 2.3% at 293 K and 10% at 150 K using an upconversion pumping mechanism. A discussion of the dynamics in this new laser material is included
