Noise in a dual dye jet hybridly mode-locked near infrared femtosecond laser

The noise properties of a near infrared hybridly mode-locked dye laser system operating in the 100 fs pulse regime are investigated. Two closely spaced cavity length values near the zero mismatch point are identified which produce distinctly different pulses. These pulse trains and the pump laser pu...

Description
Summary:The noise properties of a near infrared hybridly mode-locked dye laser system operating in the 100 fs pulse regime are investigated. Two closely spaced cavity length values near the zero mismatch point are identified which produce distinctly different pulses. These pulse trains and the pump laser pulse train are examined in the time and frequency domains for the purpose of determining their usefulness for the study of ultrafast physical processes. The differences in pulse energy fluctuation, pulse width fluctuation, and intensity autocorrelation of the two modes of operation are explained in terms of cavity detuning effects.
