Ceramization of single crystals technique was developed. Nd-doped Ca1xA0;− xYxF2 + x transparent ceramic was prepared by ceramization of single crystal. The sample exhibits high transmittance (T1053nm = 93.7%) and good mechanical properties (H = 3.4 GPa, K1c = 0.61 MPa m1/2). The continuous wavelength laser operation was obtained with an output power of 35 mW by a fiber-coupled laser-diode.
