Inkjet-Printing Produces Disposable Organic Lasers

Facebook X LinkedIn Email
An ultralow-cost fabrication method uses an inkjet printer to produce “lasing capsules” for external-cavity vertically emitting thin-film organic lasers, a development that could enable disposable laser chips. One obstacle that has limited widespread adoption of organic lasers is the fact that they degrade relatively quickly, which could be overcome if the lasers are inexpensive enough to dispose upon failure. Inkjet-printed lasing capsules serve as the core of an organic laser. Figure (a) shows a schematic of the laser setup; (b) shows actual lasing capsules, which...Read full article

    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.
