研究目的
Investigating the design and performance of a sub-10-picosecond source based on temporal focusing for delivering low-repetition-rate pulses with tunable pulse duration.
研究成果
The source delivers low-repetition-rate sub-10-ps pulses with precise short-term and long-term synchronization to a reference frequency, performing comparably to or better than several commercial laser systems, with the advantage of pulse-duration tunability.
研究不足
The non-quadratic time lens and spectral gain narrowing in a subsequent amplifier have been taken into account, but the exact impact on pulse duration and stability may vary with different equipment or conditions.
1：Experimental Design and Method Selection:
The source is based on temporal focusing implemented with a lithium niobate phase modulator and a grating compressor.
2：Sample Selection and Data Sources:
The input pulse with FWHM 50 ps is temporally modulated by a sinusoidal drive at 8 GHz.
3：List of Experimental Equipment and Materials:
Lithium niobate phase modulator, grating compressor, Mach–Zehnder modulators, Nd:YLF regenerative amplifier.
4：Experimental Procedures and Operational Workflow:
The pulse is synchronized with a maximum of the sinusoidal phase, propagates in a grating compressor, and is then amplified.
5：Data Analysis Methods:
The output pulse durations are measured and deconvolved using a high-bandwidth photodetector and a 70-GHz real-time oscilloscope.
