Abstract
A number of Raman spectra obtained for liquid and solid samples according to various electrical signals were analyzed to increase the resolution of a Raman system utilizing an optical pickup unit and pulse power. The wavelength of the laser marginally changed in response to modifications in the duty and frequency, and the accuracy of the Raman spectra changed accordingly. Intriguingly, after converting the spectrum based on the laser wavelength, an error in the Raman peak position dependent on the duty and frequency of power remained. Overall, lower duty ratio and higher frequency resulted in more accurate Raman spectra.
