The laser damage thresholds and morphologies of MgF2 crystals at 1.06 μm are reported. Strengthening of the MgF2 crystals is investigated by laser pre-irradiation and acid etching with CW CO2, XeCl and Cu vapour lasers. Ihe results show that the Cu vapour strengthening effect is the optimum and the next are acid etching and XeCl laser pre-irradiation. Strengthening mechanism is analyzed.
