研究目的
Investigating the use of MoWS2/rGO nanocomposite as a passive saturable absorber in a tunable Q-switched ytterbium-doped fiber laser (YDFL).
研究成果
The MoWS2/rGO-PVA nanocomposite serves as an effective SA for generating tunable Q-switched pulses in YDFL, demonstrating fast relaxation time and high damage threshold. This is the first demonstration of such a laser using MoWS2/rGO nanocomposite SA.
研究不足
The study is limited to the use of MoWS2/rGO nanocomposite for Q-switched YDFL and does not explore other materials or configurations. The tunable wavelength range is confined to 1028 nm to 1038 nm.
1:Experimental Design and Method Selection
The study involves the synthesis of MoWS2/rGO nanocomposite using hydrothermal exfoliation technique, fabrication of a thin film SA by mixing the nanocomposite with PVA, and its incorporation into a YDFL cavity to generate tunable Q-switched pulses.
2:Sample Selection and Data Sources
Samples include MoWS2/rGO nanocomposite and PVA thin film. Data sources include optical spectrum analyzer, oscilloscope, and RF spectrum analyzer for analyzing the laser output.
3:List of Experimental Equipment and Materials
Includes Yb-doped gain fiber, polarization independent optical isolator, tunable bandpass filter, optical spectrum analyzer (Yokogawa, AQ6370B), oscilloscope (Yokogawa, DLM2054), RF spectrum analyzer (Anritsu, MS2683 A), and optical power meter (Thorlabs, PM100USB).
4:Experimental Procedures and Operational Workflow
The procedure involves synthesizing the nanocomposite, fabricating the SA, incorporating it into the YDFL cavity, and characterizing the laser output in terms of wavelength, pulse width, repetition rate, and energy.
5:Data Analysis Methods
Analysis includes measuring the optical spectrum, time domain characteristics, and frequency domain characteristics of the generated pulses.
