    The hardness, strength, and transparency of cubic zirconia ZrO2 makes it a good candidate as a laser window material; however, to obtain these qualities a relatively large percentage of Y2O3 is added to stabilize the crystals and increase their mechanical strength. As impurities are often regarded as the initiators of laser-induced damage we have performed a study of the damage thresholds of optical quality ZrO2 stabilized with Y2O3. These thresholds have been measured with picosecond 1.06 μm laser pulses in crystals having Y2O3 concentrations of 9.4%, 12%, 15%, 18%, and 21%. We found that the addition of Y2O3 for increasing the mechanical strength of zirconia does not necessarily lead to a decrease in the damaging irradiance. In addition, the thresholds for ZrO2 are comparable to those of NaCl.
