Investigation of the Generation of Droplet Lasers
(Sumy State University, 2018) Sivni, V. B.; Hnatenko, O. S.
In this paper, the geometric parameters of liquid resonators of the type of a whisperer gallery are investigated and calculated theoretically. Namely, the laser dye Rhodamine 6G in the form of a drop on the substrate is pumped at a wavelength of 532 nm and emits a wavelength of 580 nm. The paper investigates the change in the wavelength of the radiation with a change in the droplet size. And also calculated the maximum angles of adhesion of the drop to the substrate.
Use of femtosecond lasers to encode information
(Sumy State University, 2019) Hnatenko, O. S.; Sivni, V. B.
This paper proposes a method of coding information by changing two interfering femtosecond pulses.There is no secret that using femtosecond lasers it is possible to get supercontinuum, which implies a set of discrete closely spaced spikes of radiation decomposed in the frequency domain.
