Nanosecond pulsed Ytterbium fiber laser with the polarized Gaussian beam, is utilized to form the organized periodic microstructures on the titanium surface in two different medium: air, and hydrogen peroxide (HP). SEM and profilometry analyses are used to compare the structures developed in air and hydrogen peroxide. Immersing the sample in the hydrogen peroxide medium changes the periodic space and the height of the microstructures compared to those produced in air. However, the trend of responding to the experimental parameters remains the same in both environments. XRD results demonstrate the influence of hydrogen peroxide on the titanium oxide composition, and also elaborate on the presence of Hongquiite, a very rare titanium oxide composition.
