Passively Mode-Locked Yb-Doped Fiber Laser Seeded MOPA System for High-Power Pulse Amplification
Abstract
This study presents the development of a 1064 nm pulsed fiber laser system based on a master oscillator power amplifier (MOPA) architecture. The system employs a ring laser master oscillator with polarization additive pulse mode-locking (PAPM) to generate stable pulses, while precise control to gain fiber length and cavity length ensures efficient pumping to the target 1064 nm band. Through optimized amplifier design, the system achieves 1.8 W output power with excellent spectral properties (1065.06 nm center wavelength, 0.071 nm 3-dB bandwidth). The repetition rate is tunable from 21.37 MHz to 88.11 kHz, producing adjustable pulse widths, making it suitable for high-power ultrafast applications.
