International group of researchers from the UK, Greece and Japan managed to find another use of graphene.  Now, the researchers turned to the optical properties and have created a laser based on this unique material.  Due to the lack of band gap graphene can absorb electromagnetic radiation, and then rapidly releasing it as a ray of light.     As a result, the said group of scientists managed to create graphene laser emitting ultrashort pulses lasting only a few femtoseconds (quadrillion of a second).  According to specialists, such a laser is able to generate pulses of any length, as in the infrared and in the visible spectrum.  Thermal stability of the material allows it to withstand sufficiently intense irradiation and the size of the graphene laser can be very compact .
