“…(11) Equation (11) corresponds to [21] with the additional factor y2, considering the fraction of spontaneous radiative transition from I»/2 to I, 3 [10]. Pumping directly into the lower laser level at 1530 nm leads to stimulated emission as well.…”

A computer simulation of the Er'+ 3-pm crystal laser considering the full rate-equation scheme up to the F7/2 level has been performed. The influence of the important system parameters on lasing and the interaction of these parameters has been clarified with multiple-parameter variations. Stimulated emission is fed mainly by up-conversion from the lower laser level and in many cases is reduced by the quenching of the lifetime of this level. However, also without up-conversion a set of parameters can be found that allows lasing. Up-conversion from the upper laser level is detrimental to stimulated emission but may be compensated by cross relaxation from the S3/2 level. For a typical experimental situation we started with the parameters of Er'+:LiYF4. In addition, the host materials Y3A150» (YAG), YA103, Y3Sc2A130» (YSGG), and BaY&F8, as well as the possibilities of codoping, are discussed. In view of the consideration of all excited levels up to F7/2, all lifetimes and branching ratios, ground-state depletion, excited-state absorption, three up-conversion processes as well as their inverse processes, stimulated emission, and a realistic resonator design, this is, to our knowledge, the most detailed investigation of the Er'+ 3-pm crystal laser performed so far.PACS number(s): 42.55.

“…As it was shown in previously published papers [1][2][3][4][5], ErrYLF is an efficient 2800-nm material when pumped with a high-brightness source. This makes the Ti:sapphire laser a uniquely suited pump source for Er-lasers, but for practical applications direct diode laser pumping is the preferred choice.…”

“…For this kind of application a small laser system is desirable. A good compact pumping source for the Erbium laser is a laser diode emitting at 973nm [3]. The Erbium transition 4 I 11/2 4 I 13/2 , depending on the host material, emits light of 2.7-2,94µm.…”
