Organic solid-state lasers (OSLs) are expected to achieve widespread applications due to their flexibility, tunability, and efficiency. However, they are difficult to manufacture and require over 150.000 possible experiments to find successful new materials, and discovering them will be a work of several lifetimes. In fact, according to data from the University of Toronto in Canada, only 10-20 new OSL materials have been tested in the past few decades.

Now, researchers from the university's acceleration alliance have accepted this challenge and used Autonomous Driving Laboratory (SDL) technology. Once established, they can synthesize and test over 1000 potential OSL materials and discover at least 21 OSL gain candidate materials within a few months.

SDL uses artificial intelligence and robot synthesis to simplify the process of identifying new materials. In this case, the new materials exhibit excellent laser properties. The Toronto team stated that so far, SDL is typically limited to one physics laboratory in one geographical location.

This work was described in a paper titled "Discovery of delocalized asynchronous closed-loop of organic laser emitters" in the journal Science. In this study, laboratories from Toronto and Vancouver, Canada, Glasgow, Scotland, Illinois, USA, and Fukuoka, Japan were all involved.

Each laboratory can contribute its professional knowledge and resources. This decentralized workflow is managed by a cloud based platform, which not only improves efficiency but also allows for rapid replication of experimental results, ultimately democratizing the discovery process and accelerating the development of next-generation laser technology.

"This paper demonstrates that closed-loop methods can be delocalized, and researchers can accelerate the discovery of materials in the early stages of commercialization from molecular states to devices," said Dr. Al á n Aspuru Guzik, Director of the Acceleration Alliance.
"The team designed an experiment from molecules to devices, with the final equipment manufactured in Japan. They were scaled up in Vancouver and then transferred to Japan for characterization," he said.

The discovery of these new materials represents a significant advancement in the field of molecular optoelectronics. It paves the way for the performance and functional enhancement of OSL devices, and sets a precedent for future delocalized discovery activities in the fields of materials science and autonomous driving laboratories.
