This article provides the basic information about how and why lasers work.Almost 60 years have passed since the first demonstration of a laser in 1960. After the initial spark of interest, lasers were for a while categorized as “a solution waiting for a...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 HandbookLasers for Microscopy: Major Trends: In order for biologists, drug developers, clinical lab professionals and other scientists to fully exploit new microscopy techniques and applications, parallel developments in laser technology are often required.
