The said laser beams have been created with the help of single photonic structure where photonic structure deals with the plasmonic-based photonic crystal ber (PCF) with having 5 × 5 periodic air holes with a defect at the center.The principle of generation of surgical laser beams relies on both physics and mathematics of photonic crystal ber in such way that physics deals with structure and conguration of proposed PCF including lattice spacing and diameter of air holes where mathematics manipulates with plane wave ex- pansion method to nd out the electric eld distribution in the ber. Finally, the outcomes of the works disclose that suitable conguration of plasmonic structurewith respect to green signal generates dierent type of laser beams which could be used for the biomedical application. 1. Introduction Nevertheless, the research on science and technology is burgeoning in a hasty manner nowadays, research related to medical eld needs to improve ina swift manner to solve out various problems for the necessity of society. To envisage the same, the eld of electronics vis-à-vis biotechnology and bioscience have been focused by the researchers fromboth government and non-government sectors. Again considering the medical diagnosis, the eld of optoelectronics and laser technology revolutionizes the investigation of diagnosis and clinical medicine. Further moving tolaser-based lightwave technology, it brings contact-free and keepsthe little impact on the integrity of living matter, which can easily be deployed for medical operation [1]. Furthermore, the advanced optical tech- nology such as femtosecond laser has been used nowadays to detect and monitor the cellular biochemistry, integrity of organs and characterizes the tissues. Moreover, the optical tags have been used to make the label DNA cells and the properties of blood.Again the hi-tech laser technologyhas been deployed nowadays to make the diagnosis the structure of the retina and optic nerve of the human body. Apart from this, the optical coherence tomographies have been employed in medical science to detect the precise information of retina vessel and its pigments of epithelium and choroids, etc. Furthermore, the photonics with endoscopic technology evaluates the dysfunction of swallowing and phantom. Aside from this, laser technology has been extensively used for the sake of medical therapy https://doi.org/10.1016/j.ijleo.2019.163227 Received 16 May 2019; Accepted 15 August 2019 Corresponding author.
