Broad Application Prospects Green Laser Pointer
Flexible optoelectronic device. It is an emerging electronic technology that uses organic / inorganic green laser pointer materials and electronic devices. It is fabricated on flexible / ducible substrates. With its unique flexibility and ductility, coupled with efficient and low-cost manufacturing processes, Energy, medical, national defense and other fields have broad application prospects. However, so far, for most organic semiconductor lasers, it still cannot be related to "flexibility". This is mainly due to the need for a rigid support substrate for green laser pointers.

This time. Scientists at the University of St Andrews have developed a green laser pointer method. The organic laser film is removed from the auxiliary substrate and transferred to various surfaces. Studies have shown that these flexible laser films have mechanical stability even if they are attached to another object; even without ideal storage conditions, their optical properties can remain unchanged for several months. The research team says that these ultra-thin laser films can be glued to banknotes and contact lenses, so they can be used as flexible wearable security labels. This is also feasible in theory. Because by changing the material and adjusting the grating structure of the laser. The emitted green laser pointers can display a specific series of sharp lines on a flat background-the 1 and 0 of a digital barcode.
