Mariano Troccoli, Ertugrul Cubukcu and Federico Capasso of Harvard University's Department of Engineering and Applied Physics, Alexey Belyanin of Texas A&M University, Deborah L.Sivco and Alfred Y.Cho of Bell Labs, Lucent Technologies, USA, in February The argumentation literature on the conceptual model of this device was published on Nature on the 24th. This research was partially funded by the Telecommunications and Informatics Special Research Group at Texas A&M University.
Traditional Raman lasers rely on a fundamental physics phenomenon known as the Raman effect—that is, the frequency of a monochromatic light (such as a laser) changes as it passes through a medium. A dense and intense laser beam, called a "pumping source," can cause molecules in certain media to deviate from their original position, causing some of them to lose energy. As a result, the second laser beam is generated from the medium at a different frequency than the first laser beam.
“We have been using Raman lasers for a long time,†Troccoli said. “In general, this laser requires a large and powerful external pumping source to compensate for the attenuation or attenuation of light as it passes through a substance. In our study, the pump and the material that the light passes through. Is placed in the same device."
The team's combination of energy sources and Raman matter actually created a laser in the laser, and their research has brought several key new inventions to the entire laser technology. The injection laser is the first current-driven Raman laser, and it can be used directly from the power supply.
The current creates an internal laser (pumping source) inside the substance, which in turn produces Raman laser radiation. Because the pump source is self-radiating, the instrument is slightly more efficient, with 30% of the laser pump power being converted to a Raman laser.
“This 'Russian doll'-style cascading design brings an important new physics discovery,†said Belyanin, who also provided theoretical support for writing an article on new equipment, and from 2001. At the beginning, she and Capasso's research team began to put the theory into practice. “Now the frequency of the pump source radiation can be adjusted to be the same as the strong electronic resonance inside the medium. This increases the gain of the Raman laser by five orders of magnitude, which is somewhat similar to the traditional Raman laser emitter because of its powerful absorption. They must avoid resonance.
In addition to higher performance, the device is small in size but equipped with a high-power punch.
Laser technology revolutionizes radiology to achieve "plug and play"
Engineers and applied physicists have laid the foundation for a new laser development, the Raman injection laser, and have brought several key innovations to the entire laser technology. This laser radiology instrument combines the advantages of nonlinear optics and semiconductor injection lasers. It is not only compact, but may also be widely used in imaging and probing applications one day.
