Lubeigt is researching a technique for changing the wavelength of inexpensive industrial Nd lasers from one micron to the eye-safe wavelength of 1.5 microns.
At this wavelength, lasers cannot penetrate the cornea, thus protecting the retina from damage by the laser light.
Erbium lasers are currently used to generate laser light in the eye-safe range, but the technology is not as well established as Nd lasers.
Lubeigt is working on a project to develop continuous wave (CW) Raman diamond lasers.
He has managed to get the wavelength to 1.2 microns using what is known as the Stocks effect, and will use the prize money to push the investigation forward into applying a second Stocks effect to bring it within the eye-safe range.
Lubeigt worked on the project alongside principle investigator, Dr Alan Kemp, and Dr David Burns, associate director of Strathclyde’s
