Scientists at the University of Washington have developed a laser which is nanometer sized. This has been created with the help of a semiconductor that is the thinnest. This particular semiconductor is very efficient, easy to construct, and also utilizes energy most effectively. It also exhibits high degree of compatibility with other different types of electronics. 

Lasers play a very vital role in several types of technologies, which range from medical applications to electronic components and gadgets. However, in order to meet the rising demands of communications, sensing, imaging, and computation, the experts in this field have tried developing the smallest types of laser systems which consume energy most effectively. UW nanolaser, which was created in joint collaboration with the University of Stanford makes use of a semiconductor which is tungsten based which has a thickness of only 3 atoms which is similar to the “gain material” which emits light. This recently discovered semiconductor emits lights very efficiently and is basically very thin. 

Researchers are trying to develop solar cells, LEDs, and transistors which make use of this material mainly because of the properties that it exhibits. Nanolasers are the latest types of products that the scientists are trying to produce with the help of this particular material. Nanolasers being minute can’t be observed by the human eye. However, these can be applied in several areas such as implantable microchips for monitoring health issues and the next-gen computing techniques. 

Till now Nanolasers are mostly confined to research laboratories. There are several advantages of the nanolaser created by the research team at university of Washington which are: they are highly compatible with silicon materials that are used extensively in modern day electronics and gadgets and can be fabricated also with much ease.
