Noise characterization of mode-locked lasers by comparing the power spectra of the fundamental and second-harmonic pulses

Noise characterization of mode-locked lasers by comparing the power spectra of the fundamental and second-harmonic pulses

Optics Letters 20(20): 2117-2119

By comparing the noise power spectra of the fundamental pulses and those of the second-harmonic pulses, the peak intensity fluctuation, the pulse-width fluctuation, the pulse timing jitter, and the cross correlation between the pulse width and the peak intensity f luctuations of a mode-locked pulse train can be separately quantified. The noise characteristics of an actively mode-locked Nd:YLF laser are presented to demonstrate this technique.
