Researchers used inkjet printing prepared core laser printing, laser

13 big takeaway: from Paris, France's national centre for scientific research, Mr Lai 'semiconductor physics lab and st etienne scientists at the institute of higher mining through joint efforts, through the inkjet printing prepared out of a laser core. With further development, you can use this cheap inkjet printing laser through the optical fiber transmission data, at the same time also can be used as a tool for chemical or biological sample analysis. From Paris's 13th, France's national centre for scientific research, Mr Lai 'semiconductor physics lab and st etienne scientists at the institute of higher mining through joint efforts, through the inkjet printing prepared out of a laser core. The film organic vertical launch external cavity laser capsules can be completely disposable preparation. Ink-jet printing laser capsules made by the refractive index of 1. 5 optical main base material EMD6415 ink composition, through a standard laser dye such as Pyrromethene597 or Rhodamine640 combination. Capsule is a kind of near - lumen polymer based method Perot etalon, allowing the laser output from 570 nm to 670 nm continuous tuning. Cost: a few cents while organic laser cost is low, but they will soon be the degradation characteristics has become one of the obstacles. Perhaps this barrier is not so terrible, because since the laser is so cheap, once the degradation can be thrown away. The researchers estimate that each laser capsule production costs for only a few cents. Process does not require any mask, can be done at room temperature, and can print to the flexible material. The research team used two different types of dye, to produce a range from yellow to deep red laser. They predict that other dyes can produce blue to green spectral range. With further development, you can use this cheap inkjet printing laser through the optical fiber transmission data, at the same time also can be used as a tool for chemical or biological sample analysis.
