3D Model: > "Design A Realistic And Interactive 3D Model Of A Fiber Laser System. Include Key Components: Fiber Laser Source, Collimating Optics, Beam Delivery Fiber, Focusing Lens, And The Working Table. The Laser Beam Should Be Visible As A Thin, Intense Red Line, Moving From The Source Toward The Target. Make The Model Interactive: Allow The User To Trace The Laser Path Step By Step, With Dynamic Lighting Effects Showing Reflections/refractions Through Lenses. Use A Semi-transparent Casing To Reveal Internal Components. The Environment Should Resemble A High-tech Scientific Lab With Metallic Textures And Realistic Lighting."
