Researchers at Macquarie University in New South Wales, Australia have claimed to develop world's first diamond laser. The new diamond laser has an enhanced capability to transmit heat and light effectively. The team leader of the research, Richard Mildren said that the new laser has been built by using a technique based on Raman effect. Besides demonstrating a more effective way of generating a powerful beam, it has also shown that synthetic diamonds are of the right size and quality to enable exploration of a new class of laser devices.

 

According to Mildren despite their size and appearance, diamonds made by chemical vapour deposition (CVD) diamonds used in the laser are very affordable. He said that use of natural diamonds in this type of work is very costly and problematic. Apart from these, the quality is not very consistent. Informing more about the production of diamond, the scientist said that diamonds can now be grown using a method called chemical vapour deposition (CVD) and a one cm-long crystal can be purchased for around $2,000. This method has increased the production of diamond over the last couple of years.
