Abstract

Diode pumped thulium and holmium lasers have long been thought to be the ideal solution to be problem of producing a high energy, efficient, diode-pumped, laser source due to the long upper state lifetimes. However the fundamental energy transfer process of upconversion can limit the storage of energy in the system and increase the thermal loading on the crystal. A numerical solution to the rate equations is used to model the laser performance of both 785 nm pumped Tm: YAG and 1.9 μm pumped Ho: YAG, including the effects of ground state depletion and upconversion. The benefits and problems of both systems will be discussed in detail.
