Optoelectronics devices and applications based on optical fibers become very popular in many applications. In this work, pure and doped Gold nanorods have been ablated at different pulsed laser wavelengths of 532 nm and 1064 nm, using pulse laser ablation in the liquid by using tattoo removal Nd: YAG laser (nanosecond pulses). The structural, morphological, optical, and photoluminescence properties of the ablated nanorods are studied and analyzed using X-ray Diffraction (XRD), Transmission Electron Microscopy (TEM), Ultraviolet–Visible test, and PL tests. The obtained results showed that the results of using the shorter wavelength (second harmonic generation) of the laser used in ablation were the best in all tests and analyses. The obtained by using the second harmonic generation was the highest intensity and the longest, with a length of approximately 7 µm, and the results of optical analyzes using the visible ultraviolet rays test, and the PL test showed higher intensity in addition to a shift towards blue wavelengths caused by the denser nanorods and more crystallization. From the previously presented results, we conclude that the obtained nanorods can be used in electro-optical and photonic applications, and even in different types of optical sensors.
