Reaction of laser plasma on Nd:YAG with a high optical mass.

Traditional material processing techniques such as material cutting, thin plate drilling, and surface processing are replaced by laser material processing (LMP). When a high-energy laser is projected onto a material, the temperature of the substance rapidly rises, changing its properties and causing the material on the surface to evaporate and peel off. In this study, we used a Quantel Brilliant neodymium-doped yttrium aluminium garnet (Nd:YAG) laser with a wavelength of 1064 nm, a pulse width of 5–6 ns, a beam diameter of 6 mm, and a 10 repetition rate (Hz) on the energy stability is within 5.60 percent, and an F-theta lens to obtain a focused laser beam with a diameter of 0.2 mm.
