The world around us is constantly in motion and many of the ways in which the world is shaped use technology that was not available just a century ago. An example of this is the fact that many parts of industry are now using laser tools in order to accomplish a purpose much faster and more accurately than what was done before lasers were available. This is sometimes done on a very large scale, such as the laser powered measuring tools that was used to determine an accurate distance from the Earth to the moon. You also have the diode module laser which allows you to use various tools with low power consumption and in smaller sizes. These types of tools are not only used in industry, they help in the scientific and medical fields as well.
You’ll be interested in knowing that diode lasers may come in a variety of different colors. Most of us think about lasers in the red color and although red beams are commonly used, they are by no means the only option that is available. You can also find lasers in green, violet and blue as well as in other colors, depending upon your needs. Why are these items used in different colors? Because the color makes a difference in its ability to be seen. For example, green lasers are used when greater contrast is necessary and red lasers are used in darker conditions. Understanding these differences can help you to choose a laser that is going to be right for you and will also increase your appreciation for this common tool. (Source: Coherent Laser Tools)
