The research is reported in the journal “Soft Matter” and the full article can be found here.
A laser is a characteristically “pure” form of light, occupying a very narrow wavelength range, or colour. Laser devices are already ubiquitous in modern life; they are used to read data from Blu-Ray discs and deliver high-speed internet around the world, for example. In science and technology, lasers are similarly versatile – being employed for a wide range of purposes such as medical treatment and testing, or space-based remote sensing.
Today, most lasers are made on silicon wafers using expensive processes similar to those used to make microprocessors. However, scientists have now designed a process to “print” a type of organic laser on any surface, using technology very similar to that used in the home.
