Investigation of the laser and optical properties of Nd3+:Ba(Zr, Mg, Ta)O3 ceramic, Nd3+(Na+):Ca2MgSi2O7 single crystal, and Yb3+:Lu3Al5O12 ceramic

We report three new laser materials. Nd 3+ -doped Ba(Zr, Mg, Ta)O 3 ceramic indicates a broadband luminescence spectrum due to its disordered structure. By optimizing the manufacturing process and laser configuration, high output power and high slope efficiency operation was obtained. Nd 3+ (Na + ):Ca 2 MgSi 2 O 7 shows another type of spectral broadening caused by its structural modulation. In the input–output property, an anomalous behavior due to phase transition was observed. Yb 3+ :Lu 3 Al 5 O 12 is one of the important laser materials for thin-disk laser because it indicates mild reduction of the thermal conductivity as an increase of concentration. The highly efficient CW laser operation is reported.
