Uses of a Laser Module

Tags:DinoDirect Electronic Laser

Laser modules can do a number of incredible things. The special qualities make them particularly useful in recording, storing and transmitting many kinds of information. A laser module also is valuable in such activities such as scanning. heating, measuring and guiding. As a result of their wide use, most laser modules can be found in equipment used in homes, factories, office, hospitals and libraries.

a line of light is actually a rapidly moving laser beam scanning a bar code. A bar code consists of a pattern of lines and spaces on packages that identifies the product. The scanner reads the pattern produced from the laser module and sends the information to a computer in the supermarket. The computer identifies the items’ price and sends the information to the register.

A laser module’s beams’ highly focused energy can produce a great amount of heat. Industrial laser modules, for example, produce beams of thousands of watts of power. They cut and weld metal, drill holes and strengthen materials by heating them. Industrial lasers also cut ceramics, cloth and plastics.

People also use green laser modules to measure distance. An object’s distance can be determined by measuring the time pulse of laser light takes to reach and reflect back from the object. Laser devices used to measure shorter distance are called range finders. Surveyors use the devices to get information needed to make maps.

A laser’s strong straight beam makes it a valuable tool for guidance. Instruments called laser gyroscopes use the laser beams to detect changes in direction. These devices help ships, aero planes and guided missiles to stay on course. A laser varies greatly in size. There are three main parts in a laser module. These parts are an energy source, an active medium and an optical cavity. These three put together make the laser module in working condition.
