The background image depicts a yellow semiconductor disk laser developed at the Optoelectronics Research Centre (ORC). The semiconductor gain structure emits invisible infrared radiation. To generate yellow laser light, the wavelength is halved using a nonlinear crystal. In the image, the laser beam has been split into multiple beams by means of a so-called diffractive element.
The development of an optically pumped yellow semiconductor disk laser is part of the BRIGHTLASE project at ORC.
The technology offers powerful means to develop lasers with unique properties, such as wavelength tunability, power scalability and narrow spectrum, and with potential applications spanning areas as diverse as medicine, astronomy and spectroscopy. One of the medical applications of yellow lasers is photothermolysis for the treatment of various skin conditions.
