Optical bistability in the operation of a continuous-wave diode-pumped Yb:LuVO(4) laser.

We report on sizable optical bistability in the operation of a continuous-wave diode-pumped Yb:LuVO(4) laser, as a result of the resonant reabsorption losses in the laser crystal which increase with the temperature. Significant intensity fluctuations have been observed in a small operational region near the critical point.
