Longer Duration Time Achieved for Continuous-Wave Organic Lasing

FUKUOKA, Japan, May 5, 2017 — An optically pumped organic thin-film laser has shown the ability to continuously emit light for 30 ms — more than 100 times longer than previous devices. Organic thin-film lasers use a thin layer of organic molecules as the laser medium. By designing and synthesizing molecules with novel structures, they can achieve a wider range of colors than inorganic lasers, making them well-suited for photonics applications.

    thin film
    A thin layer of a substance deposited on an insulating base in a vacuum by a microelectronic process. Thin films are most commonly used for antireflection, achromatic beamsplitters, color filters, narrow passband filters, semitransparent mirrors, heat control filters, high reflectivity mirrors, polarizers and reflection filters.
