Kurzfassung
By applying a magnetic field to the terahertz intracenter silicon laser the degeneracy of the donor states is lifted. In the case of a bismuth doped silicon laser operating at 6 THz it is demonstrated that this effect can be used to tune the emission frequency. The frequency change depends on the relative orientation of the magnetic field and the crystallographic axis of the laser. The tuning rate is 40 - 60 GHz/T. The frequency tunability is explained by the linear Zeeman effect which splits the 2p<sub>/pm</sub> donor state acting as the upper laser level in the Si:Bi laser.
