研究目的
Investigating the effect of polarization modulation on the stability of a 1.5 μm laser locked to a fibre cavity.
研究成果
The study demonstrates that polarization modulation effects limit the stability of the frequency lock of a laser onto a fibre cavity mode, with a stability level of 10-12 being achievable under optimized conditions.
研究不足
The stability of the frequency lock is limited by polarization effects induced by the electro-optic modulator, including residual amplitude modulation and signal distortion due to the cavity's slight birefringence.
1：Experimental Design and Method Selection:
The study involves analyzing the limitations introduced by a fibre connectorised Lithium-Niobate electro-optic modulator on the stability of a laser locked to a fibre cavity. The methodology includes phase modulation of the laser beam and detection of the output signal through an optical circulator and a photodiode.
2：Sample Selection and Data Sources:
A ring fibre optical cavity is built using a 10/90 optical coupler and 12 m single-mode optical fibre. The cavity length is controlled by a piezoelectric transducer (PZT) tube.
3：List of Experimental Equipment and Materials:
Extended cavity diode laser (ECDL), electro-optic modulator (EOM) (iXblue Photline MPX-LN-0.1), optical circulator, photodiode, lock-in amplifier, piezoelectric transducer (PZT) tube by Morgan Technical Ceramics.
4：1), optical circulator, photodiode, lock-in amplifier, piezoelectric transducer (PZT) tube by Morgan Technical Ceramics. Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The laser beam is phase-modulated by the EOM before being coupled into the cavity. The output signal is measured and used as an error signal to control the ECDL optical frequency.
5：Data Analysis Methods:
The detected signal is analyzed for offset and distortion due to polarization effects.
