Abstract

Although pump energy is mainly absorbed at the border of a heavily doped YAlO3:Er3+ rod, fundamental mode laser operation is achieved. The absorption of pumplight in the laser rod, energy transfer mechanisms and the population of the laser levels are discussed. A possible explanation of the inversion maximum in the center of the rod is given.
