研究目的
Demonstrating a passively Q-Switched fiber laser employing graphite oxide as a saturable absorber, obtained by recycling graphite from Li-ion batteries, to generate tunable microsecond pulses with kHz repetition rates.
研究成果
The study successfully demonstrated the use of recycled graphite oxide as a saturable absorber in a Q-Switched fiber laser, achieving stable pulse generation with low pumping thresholds. This approach offers a promising method for recycling spent lithium-ion batteries, contributing to environmental sustainability.
研究不足
The use of nitric acid for graphite recovery poses environmental concerns. The method's scalability and environmental impact need optimization for large-scale applications.
1：Experimental Design and Method Selection:
The study employed a passively Q-Switched laser configuration with a ring cavity structure, using graphite oxide as a saturable absorber.
2：Sample Selection and Data Sources:
Graphite oxide samples were obtained from recycled Li-ion batteries through a chemical separation and oxidation process.
3：List of Experimental Equipment and Materials:
A 20 m erbium-doped fiber amplifier (EDFA - Thorlabs-M12-980-125) was used as the gain medium, pumped by a 1474 nm tunable laser diode.
4：Experimental Procedures and Operational Workflow:
The graphite oxide was placed between the end face of two FC/PC optical fiber connectors to interact with the laser beam. The laser output was extracted via a 10:90 output coupler.
5：Data Analysis Methods:
The optical spectrum and radio frequency trace were measured to analyze the laser output.
