Introduction

Core parameter measurement technology solution

Measurement items	Scope of application	Optimal method	Uncertainty range
Pulse width	3fs-250ms	Autocorrelation method	<5%
Rise time	>10ps	Photoelectric detection method	10-15%
Repetition rate jitter	kHz-GHz	Harmonic analysis method	<100fs

Technological Innovation and Practical Verification

Breakthrough introduction of the ultrafast diagnostic dual-track mechanism: combining the time-frequency analysis module with the third-order autocorrelation optical path:

Optical path stability is improved to 0.02λ@632nm
Transfer matrix calibration is used to ensure phase matching of the third-order nonlinear response

Actual measurement case: The temperature drift of the

autocorrelator measured using a femtosecond optical shutter is controlled within ±0..1℃

Metrology traceability system

Key parameters	Calibration benchmark	Environmental compensation model
Laser pulse width	JJF1493-2014	β=1.53e-4/℃
Time jitter	NIST-PTB joint traceability chain	Multi-party reflection delay correction
