Study the delay time influence on the R6G dye attenuation coefficient utilizing laser probe technology

Abstract

This study involved using a diode laser emitting light at a 650 nm wavelength. A continuous-wave laser was converted into a pulsed laser through the application of a PWM circuit. A solution of laser dye was prepared by dissolving the dye in distilled water at a concentration of 104 M. The setup included components such as a wave splitter, mirrors, a motorized delay stage, and a spectrograph to analyze the spectrum emitted by the dye laser and transmitted via an optical cable. An exploration was conducted to understand how the delay time impacts the absorption coefficient of the laser dye. The results demonstrated a relationship between delay time and absorption. Pulse width. Changes in the input power affected the sample response. The absorption coefficient can vary nonlinearly based on pulse changes. These data illustrate how energy is focused on the sample over different durations. Adjusting the delay time can influence the absorption coefficient, indicating how the delay time affects the dynamics and interactions directly or indirectly. These discoveries confirm the importance of interactions between samples and variations in concentration on the absorption coefficient.
