Abstract:
This project investigates the feasibility of producing high-quality, high-reliability laser beams from traditional handheld laser pointers. The goals of this project included understanding the fundamental principles and functionality of a handheld laser pointer as well as conversion of said laser pointer to a setup that could be used in a research-level capacity. To achieve these goals, handheld lasers were disassembled to their component parts, and extensive testing was performed on the maximum capabilities of the laser pointers. Data was collected on the maximum supplied current the laser diode could withstand, the viability of creating a tunable intensity laser and the potential for making a reproducible product. In the testing process, the converted laser pointers were found to be reliable if constrained to a limited current. Additionally, the laser beam was successfully made to have a tunable intensity by varying the supplied current. Additional testing will be performed to determine the lifespan of the converted laser pointer as well as the reproducibility of the project for use in a research setting.
