One manufacturer of fiber laser systems offers supercontinuum breakthrough. The fact is that supercontinuum generation is considered to be based on intense laser beam light of one color that runs within a material, similar to glass, and increases into a spectrum of colors. Such fiber laser technology allows emitting laser beam light at colors required for such specific applications as bioimaging, optical communications, and essential investigations of materials.
It should be noted that until recent times, two ways to produce a supercontinuum are distinguished. The first way includes the application of a thin optical fiber to concentrate laser beam light to high intensity over lengths of a few meters. The second way supposes the focus of more powerful laser beam light from an amplified laser system on the standard glass.
Nevertheless, all these techniques have several disadvantages, for instance, huge size, complexity and high cost of applying a high-quality laser beam or the accurate and fragile tuning required to emit fiber laser light into an optical fiber that is only two-thousandths of a millimeter in diameter. Nowadays a team of researchers from Scotland has presented a new fiber laser technology for reaching the supercontinuum generation.
To be more precise, employing the novel technique, the researchers succeeded to produce a wide range of colors from a single laser system. The new fiber laser technology is based on the combination of a conventional laser system with a special, nonlinear crystal leading to designing a supercontinuum directly. Additionally, there is no need for either a high-power fiber laser or delicate coupling of laser beam light into thin optical fibers.
The team claims that the operating principle is totally new: “our specially engineered gallium phosphide crystal creates a cascade effect.” The thing is that the crystal is illuminated with laser beam light from an infrared laser system, and some of these beams are changed to visible green light. This, in its turn, produces more green laser beam light at a slightly longer wavelength, becoming first yellow, then orange, and working all the way out to the red.
Moreover, it is possible to generate green laser beam light at longer and longer wavelengths from the weaker edges, herewith, this fact has never been reported before. The researchers plan to expand the spectrum of the fiber laser light and to make them more intense by optimizing the features of the crystal. Nonetheless, further improvements are required to detect whether the effect is specific to the special gallium phosphide crystal that is applied.
