研究目的
Demonstrating a high-power broadband linearly-polarized supercontinuum (LP-SC) laser source using a few-mode polarization-maintaining photonic crystal fiber (PM-PCF).
研究成果
The study successfully demonstrates a high-power LP-SC from few-mode PM-PCF with a spectrum spanning from 480 to 2400 nm and a maximum average power of 77.3 W. The intermodal FWM effect significantly blue-extends the spectrum.
研究不足
The technical constraints include the need for precise alignment and thermal management. The application constraints are related to the specific requirements for high-power and broadband LP-SC generation.
1：Experimental Design and Method Selection:
The experiment involves coupling the output of a polarization-maintaining picosecond master oscillator power amplifier (PM-MOPA) at 1064 nm into a few-mode PM-PCF to generate a high-power broadband LP-SC.
2：Sample Selection and Data Sources:
A 7 m long PM-PCF is used for LP-SC generation.
3：List of Experimental Equipment and Materials:
PM-MOPA, PM-PCF, PM-CIR, PM-YDF, PM-MFA, and a water-cooled heat sink.
4：Experimental Procedures and Operational Workflow:
The PM-MOPA delivers 150 ps pulses at 80 MHz with
5：4 W average output power. The output is coupled into the PM-PCF to generate the LP-SC. Data Analysis Methods:
1 The spectrum and power of the LP-SC are measured and analyzed.
