We have demonstrated simultaneous lasing and self-frequency doubling of a neodymium and germanium doped silica fiber laser at 1.06 pm. The doubling action is provided by a self-organized phase matching grating in the fiber. The laser was modelocked using a linear external cavity which produced 600 ps pulses at 1.06 pm.

A Master Oscillator Power Amplifier configuration using a Nd:YAG single-crystal fiber to amplify a passively Q-switched microlaser is presented. We achieved the amplification of 80 μJ, sub-nanosecond pulses to the multi-millijoule regime. OCIS codes: (140.3580) Lasers, solid-state; (140.3480) Lasers, diode-pumped; (140.3530) Lasers, neodymium; (140.3380) Laser materials; (060.2290) Fiber materi...

The development of a recycling process for rare-earth-containing waste is important improving the resource conservation and security rare-earth metals. Phase equilibria between molten fluoride oxide were investigated to develop novel neodymium magnets based on flux-remelting method. LiF—rare-earth (REF3, RE = Nd, Dy) mixtures oxides (RE2O3, selected, phase in Nd2O3−NdF3−Li2O−LiF Dy2O3−DyF3−Li2O...

The study involved preparing a new compound by combining Schiff bases generated from compounds for antipyrine, including lanthanide ions (lanthanum, neodymium, erbium, gadolinium, and dysprosium). preparation of the ligand condensation reactions (4-antipyrinecarboxaldehyde with ethylene di-amine) at room temperature, was characterization using spectroscopic analytical studies ( FT-IR, UV-visibl...
