According to a report from Maims Consulting, scientists at the University of St. Andrews in the UK recently stated that they have made a "significant breakthrough" in the decades of challenges in developing compact organic semiconductor laser technology. 

Firstly, an OLED with a world record light output was manufactured, and then integrated with a polymer laser structure. This new type of laser emits a green laser beam composed of short light pulses.

Structure of electrically driven organic semiconductor lasers
The paper published in the journal Nature explains how the research team at the University of St. Andrews overcomes common organic semiconductor problems such as low current density and intolerable losses caused by injecting charges into the gain medium.
The paper points out that "researchers have achieved loss reduction by developing an integrated device structure that effectively combines OLEDs with extremely high internal light generation capabilities with polymer distributed feedback lasers. Under the electrical driving of the integrated structure, the threshold of light output and driving current can be observed, with a narrow emission spectrum and the formation of a laser beam above the threshold.

The research results provide an organic electronic device that has never been proven before, and indicate that indirect electric pumping of OLEDs is a very effective method for achieving electrically driven organic semiconductor lasers. This provides a method for visible light lasers that can be applied in the fields of spectroscopy, metrology, and sensing.

The conclusion of the paper is: "Researchers have demonstrated an integrated device method that can achieve electrically driven lasers in organic semiconductors, thus solving an important challenge in organic optoelectronics. This method overcomes the main difficulties commonly encountered in direct electrical injection attempts of organic or hybrid perovskite lasers, while retaining operational advantages.
