Abstract : A new class of solid-state laser which employs self-pumping from internal laser transitions to achieve inversion in other transitions. A LiYF4 laser having an activator of trivalent holmium is pumped by a standard flashlamp or by a doubled Nd laser to populate the 5S2 manifold. Inversion is achieved between 5S2 and 5I5 at 1.4 micrometers. Employing appropriate mirrors, inversion is then produced between 5I5 and 5I7 at 1.7 micrometers. Finally inversion is obtained between 5I7 and 5I8 at 2.06 micrometers. (Author)
