ABSTRACTLaser pulse melted single crystals of several metals have been examined by the Rutherford backscattering/channeling technique and with optical and scanning electron microscopy. Metals belonging to the three major structure groups; fcc (Ni, Pd, Rh); bcc(Mo, Nb, W, Fe); and hcp (Be, Ti, Re) have been studied at various laser power levels and in different crystallographic orientations. Of these cases, Be, Ti and Fe show high temperature allotropes which are expected to influence the character of the resolidified surface layer.

ABSTRACTEfficient, phase-matched second-harmonic generation of 1.064 µm radiation has been observed with single crystals of 4-aminobenzophenone (ABP). These crystals are tr nsparent from 420–2000 nm and have damage thresholds exceeding 30 GW/cm2 (for a 30-picosecond laser pulse).
