Scientists at the Institute of High Current Electronics (ISE SB RAS) have just created a unique white continuous spectrum laser. This is the world's first device to produce white light from a single laser source by evenly mixing all colors of the visible spectrum.
According to Vladimir Prokopyev, senior researcher at the Gas Laser Laboratory, in microscopy, a white laser will allow one to obtain more contrast images and study cells and tissues in detail, and in medicine, more detailed images of internal organs and tissues. It can also be used in airborne remote sensing to analyze various impurities and gases in the atmosphere.
Russian and foreign scientists have been trying to create lasers for many years. But no one can get away with multicolor – white light is obtained only by combining many laser beams of different colors.
“We used a powerful femtosecond laser, which generates pulses of such short duration that the light has time to travel a distance less than the thickness of a human hair. We focused it in a certain way and obtained radiation with an extremely wide spectrum, which is perceived by the human eye as a beam of white light,” said Dmitry Lubenko, a junior researcher at the Gas Laser Laboratory.
Now Tomsk scientists continue to improve the white laser to make it more efficient and precise, while reducing its size.
