dear ravil,
if we short the pump wavelength , the energy will be more, but the conversion efficiency is low, due to the exists if EXCITED STATE OF ABSORPTION , and the emission will be only between 2 energy levels, if u increase the energy levels, the population inversion not optimizing properly, i might be thought , that u can increase the erbium concentration on core ..
