How that definition translates into technically correct quantification methods is the focus of this article.That portion of the spectrum that the eye can see — and its rainbow of colors — is rather small, covering approximately 360 to 830 nm. What colors we perceive depends on wavelength, while...Photonics HandbookFiber Lasers: New Types and Features Expand Applications: Since its inception, the fiber laser has attracted users because of its large gain and the ability to produce continuous lasing. The quasi-continuous wave for industrial applications further broadens fiber lasers’ appeal.The modern fiber laser is pumped by high-power, multimode single-emitter diodes or diode bars, typically through a cladding surrounding a single-mode core. This single-mode core is typically 5 to 12...Photonics HandbookAspheric Lenses: Design Considerations: This first of two articles will cover design and manufacturing options for aspheres; the second will include more detail on manufacturing and testing processes. These articles will provide the tools optics designers need to tailor their designs to the appropriate manufacturing process and to optimize the cost of component fabrication.Aspheric surfaces are powerful tools that combine the optical corrections of multiple lenses into a single element (Figure 1) and affect performance in ways that spherical optics cannot. For example,...Photonics HandbookLasers: Understanding the Basics: Although lasers range from quantum-dot to football-field size and utilize materials from free electrons to solids, the underlying operating principles are always the same.
