Optical Characterization or Cr3+:YGAB and Cr3+:YGAB Crystal for selr-frequency-doubling Laser
Abstract：Cr3+:YAB and Cr3+:YGAB crystals have broad fluorescence spectra ranging from the red to near-IR region. The optical gain of Cr3-:YAB crystal was measured in the range from 744 urn to 852.5 nm. The maximum single-pass gain was 1.9 at 820 nm. Second harmonic generation in the UV region(375 nm) was obtained by a Cr3-: YAB crystal with the conversion efficiency 1.5 times as high as that of LBO crystal.Keywords：Self-frequency-doubling;UV laser;Cr3+-doped crystal- 51

Investigation of Corrosion Resistance or Ni-Fe Alloy on matrix of Nd-Fe-B
Abstract：The electrodeposition of Ni-Fe Alloy on the matrix of Nd-Fe-B was investigated in detail. The phase structure was γ and α phase, the percentage of iron in the alloy deposits ranged for 18% to 25%. The corrosion resistance of Ni-Fe ally deposits plated directly on the matix of Nd-Fe-B was in proportion to Ni deposits. The corrosion resistance of Ni-Fe alloy deposits previously plated Cu on the matrix was greater than that of Ni deposit on Nd-Fe-B matix.Keywords：Electrodeposition;Double phase alloy;Corrosion;porosity- 54

Super-fine Diamond Tools for Ruling Diffraction Gratings
Abstract：Diffraction gratings are very accurate optical elements,which are ruled by diamond tools usualy. In order to get higher diffraction efficiency of gratings, the angles of ruling tools must be very accurate. Chosing the direction of diamond lattice is very important for raising service life of’ the tools. The smooth finish at the edge of the tools is better than 8nmRa.Keywords：diamond tool;diffraction grating- 44
