Spectrally broad laser radiation from continuous wave (cw) lasers can exhibit second-order autocorrelation traces virtually indistinguishable from those of mode-locked lasers. Consequently, based only on autocorrelations, one might erroneously conclude that a cw laser is mode-locked. Such misinterpretations can be avoided by carefully characterizing radio frequency transients and spectra. However, optoelectronics are often too slow for lasers with an axial mode spacing in the multi-GHz range. Carefully evaluated autocorrelations then remain the last resort for validating mode locking. We compare autocorrelation measurements and calculations of a mode-locked titanium-sapphire (Ti:Sa) laser and a spectrally broad monolithic cw Ti:Sa laser to illustrate the ambiguity of optical autocorrelation.
