A new type of laser has been discovered which can emit a wide range of colors for longer width, i.e. 30ms. This new organic laser can be applicable for communications and displays. A research conducted on this new type of laser can bring extended lasing reality one step closer.
As Phys.org cited, an optically pumped organic laser having a very thin film has been discovered which can emit light without any break for continuous 30ms. This is 100 times longer than any laser devices known till date. The research was carried out at Kyushu University's Center for Organic Photonics and Electronics Research (OPERA).
Not at all like the inorganic lasers normally found in CD drives and laser pointers, thin-film organic lasers utilize a thin layer of organic molecules as the laser medium, which is the material in the gadget that really creates lasing by producing and intensifying light when energized with an energy source. In the case of research testing, the energy source was exceptional bright light from an inorganic laser.
With the help of organic laser having a thin film, it is possible to achieve the colors which are usually difficult in the case of inorganic lasers. Science News Line reported that if the molecules are designed and synthesized with new structures, any color of the rainbow light emission is possible. Organic thin film lasers were a part of the study from a long time, but problems got arise such as limiting the duration of light emission due to degradation and loss processes.
Scientists have now successfully reduced the previous limitation of the duration of light emission problem and extended the duration of lasing with a combination of three strategies which have been used in the study of the thin-film organic laser. The research is still in progress to further sustain the light emission from the organic thin film laser for a longer duration. Scientists now aim to realize organic thin film laser with electricity as the main energy source.
