研究目的
To demonstrate a synchronously self-Q-switched and self-mode-locked output pulse fiber laser based on a linear compound resonator and an LD cladding-pumped Yb-doped double-clad fiber, and to study its characteristics and applications.
研究成果
The study successfully demonstrated a synchronously self-Q-switched and self-mode-locked output pulse fiber laser with significant achievements in pulse width, energy, and repetition rate. It also observed pulse splitting of the self-Q-switched envelope, achieving up to 14 subpulse packets.
研究不足
The technical constraints include the complexity of the system and the difficulty in operating it. Potential areas for optimization include increasing the efficiency of ablation of materials.
1：Experimental Design and Method Selection:
The experiment is based on a linear compound resonator and an LD cladding-pumped Yb-doped double-clad fiber.
2：Sample Selection and Data Sources:
The output pulse laser from mirror M3 is detected by a high-speed detector.
3：List of Experimental Equipment and Materials:
Includes a (2+1)×1 pump/signal combiner, Yb3+-doped fiber, flat mirrors M1, M2, and M3, a DH-GDT-D007NB high-speed detector, and a digital phosphor oscilloscope.
4：Experimental Procedures and Operational Workflow:
The pump light from the LD is launched into the Yb3+-doped fiber, and the output pulse laser is detected and analyzed.
5：Data Analysis Methods:
The signal from the detector is conveyed to a digital phosphor oscilloscope for analysis.
