研究目的
Investigating the generation of wavelength-tunable square pulses based on dissipative soliton resonance in an Yb-doped passively mode-locked fiber laser.
研究成果
The study successfully demonstrates the generation of stable, wavelength-tunable square pulses in a passively mode-locked Yb-doped fiber laser operating in the DSR regime. The independence of DSR from lasing wavelength and the linear increase in pulse duration with pump power are key findings, offering insights for designing high-power lasers in the DSR regime.
研究不足
The study is limited to the specific configuration of the Yb-doped fiber laser and the effects of polarization controller adjustments on wavelength tuning. Potential areas for optimization include exploring other fiber types or configurations for broader wavelength tuning ranges.
