Abstract The collisional broadening of the 21Σ＋→61Σ＋ line of NaK molecule was studied using the optical-optical double resonance technique. A single-mode diode laser was set to a particular 11Σ＋(v″，J″)→21Σ＋(v′，J′) transition. Another single-mode diode laser was then used to excite the molecule from 21Σ＋(v′，J′) level to the rovibrational level of 61Σ＋. The two laser beams counterpropagated through the cell. The broadening rate coefficient was determined from the slope of the total linewidth versus potassium density curve. The rate coefficient, kbr=(1.4±0.7)×10-8 cm3·s-1,was obtained. The collisional excitation transfer between rotational levels of the 21Σ＋ state[i.e., 21Σ＋(v＝8，J＝12)→21Σ＋(v＝8，J＝13，14)] was also investigated. The rates can be determined from the relative intensities of the main peak and satellite lines, combined with a rate equation model. The rates are 6.1×106 and 5.2×106 s-1 respectively.
