Abstract

Optical laser engineering deals with the design, development, and application of laser systems that generate highly focused and coherent light. This field plays a crucial role in industries such as medical surgery, telecommunications, material processing, defense, and scientific research. Engineers work on improving laser efficiency, wavelength control, beam quality, and safety. Optical lasers are widely used in fiber-optic communication, laser cutting and welding, barcode scanners, and advanced imaging technologies.
