Diamonds A Lasers Best Friend
Researchers have shown that diamonds can radically improve the quality of high power laser beams. According to new photonics research by Laser & Photonics reviews, by exploiting optical interactions inside a diamond crystal can increase the brightness of the output beam by 50%.
Lasers come in various colors and with various beam powers found in DVD players all the way up to lasers capable to burn through steel. Putting aside these differences, the one fundamental property that is crucial to applications, is its quality (also known as coherence). High quality lasers are required to meet growing technological demands in applications such as remote sensing and in defense.
The major advantage of using a diamond over standard methods of converting a laser beam in a second laser is that it can dissipate heat faster than other optical materials. Also, conversion can be achieved passively in a very small package.
This useful property has enabled the researchers to demonstrate the simultaneous conversion of a high power laser with poor beam properties to a bright beam in a part of the infrared spectrum called the eye safe region.
