How Distance Between Reflections, Angle of Reflection, and Quantity of Reflections Affect the Light Amplified by Stimulated Emission of Radiation
The objective of this experiment was to find out how the quantity of reflections, the angle of reflection, and distance between reflections will affect the intensity of a laser, or light amplified by the stimulated emissions of radiation. This was achieved by setting mirrors up with the correct angles, distances, and number of actual mirrors. The angles used were; 30, 45, and 60 degrees, the number of reflections used were; 1, 5, and 10, and the distances used were; 0.45, 0.8, and 1.15 meters. A laser beam was then bounced off each mirror, and the energy was measured by a volt meter attached to the solar panel after the last reflection. After conducting the experiment and analyzing the data using a 3-factor D.O.E., it was found that the only significant factor was the quantity of reflections effect. In this effect, there was a significant loss of intensity.
