Abstract :
We report, for the first time to our knowledge, the generation of titanium oxide nanoparticles in water using a high-power high-brightness continuous wave (CW) fibre laser source at 1070 nm (IPG Single mode YLR-1000-SM 1 kW fibre laser). Fibre laser sources are robust and easy-to-use. The output beam quality is determined by the waveguiding properties of the doped core and hence the output beam can be focused to a very small spot with relatively large depth of focus. Therefore the material processing/ablation/removal can be considerably directed/tailored as desired.
