a, Normalized optical intensity profiles of the REMPI laser pulses. The red trace corresponds to the 648 nm or 674 nm lights, and is proportional to \({\varOmega }_{01}\). The green trace corresponds to the 532 nm light, and is proportional to \({\varGamma }_{{\rm{ion}}}\). b, The Doppler factor FDoppler(v) versus the velocity of the K2 product. The lower and upper bounds correspond to \({\varGamma }_{{\rm{i}}{\rm{o}}{\rm{n}}}/(2{\rm{\pi }})\) at peak values of 6 MHz and 14 MHz, respectively.
