Abstract
We characterize the optical bistability observed in a diode-pumped Yb:GdVO4 laser operating in the continuous-wave regime at room temperature. The bahavior of this laser is rather complex as a result of the coexistence and switching between the σ and π polarization states characteristic of this uniaxial crystal. The bistability range extends over more that 1 W in terms of absorbed pump power while the output power at the up-threshold increases abruptly from 0 to 0.71 W. We analyze in more detail the influence of the Yb concentration, the crystal thickness, the output coupling, and the cavity configuration on the bistability.
