The main objective of this PhD thesis was to implement solid-state lasers based on codoped Yb3+:Er3+ phosphate glasses pumped by laser diode and to study their behavior when submitted to an optical feedback. This kind of lasers presents as main advantages a very high sensibility to the optical feedback due to the optical properties of the Er3+ ion enhancing the relaxation oscillations. Moreover, the emission wavelength around 1,535 µm belongs to the eye safe spectral domain. First, we have established the rate equations of the population inversion and the electric field for a three-level laser (Yb:Er) submitted to an optical feedback. We have done a comparative study of the influence of the amplifying medium (three-level system Yb:Er or fou...
