11Laser safety — A typical laser warning symbol. Laser safety is safe design, use and implementation of lasers to minimize the risk of laser accidents, especially those involving eye injuries. Since even relatively small amounts of laser light can lead to… …
12Laser pointer — A laser pointer is a portable, pen sized laser designed to be held in the hand, and most commonly used to project a point of light to highlight items of interest during a presentation. Most laser pointers have low enough power that the projected… …
13laser — /lay zeuhr/, n. Physics. a device that produces a nearly parallel, nearly monochromatic, and coherent beam of light by exciting atoms to a higher energy level and causing them to radiate their energy in phase. Also called optical maser. [1955 60; …
14Pump (disambiguation) — A pump is a mechanical device used to move fluids and slurries.Pump may also refer to: * Ion pumps (Ion transporters) in cell membranes * Pump (shoe) * Pump (album), by Aerosmith * Pump can refer to two different Caribbean drums, one each used in …
15Fiber laser — A fiber laser or fibre laser is a laser in which the active gain medium is an optical fiber doped with rare earth elements such as erbium, ytterbium, neodymium, dysprosium, praseodymium, and thulium. They are related to doped fiber amplifiers,… …
16Dye laser — Close up of a table top dye laser based on Rhodamine 6G, emitting at 580 nm (yellow orange). The emitted laser beam is visible as faint yellow lines. The orange dye solution enters the laser from the left, and is pumped by a 514 nm (blue green)… …
17Disk laser — Not to be confused with Laserdisc. Fig.1. An optically pumped disk laser (active mirror). A disk laser or active mirror (Fig.1.) is a type of solid state laser characterized by a heat sink and laser output that are realized on opposite sides of a …
18Active laser medium — The active laser medium or gain medium is the source of optical gain within a laser. The gain results from the stimulated emission of electronic or molecular transitions to a lower energy state from a higher energy statepreviously populated by a… …
19Diode-pumped solid-state laser — A frequency doubled green laser pointer, showing internal construction. Cells and electronics lead to a laser head module (see lower diagram) This contains a powerful 808 nm IR diode laser that pumps a Nd:YVO4 laser crystal, that in turn outputs… …
20Fiber disk laser — A fiber disk laser is a fiber laser with transverse delivery of the pump light. They are characterized by the pump beam not being parallel to the active core of the optical fiber (as in a double clad fiber), but directed to the coil of the fiber… …
