用质谱仪作为双光子响应探测器组成的自相关器测量了钛宝石激光器的二次和三次谐波辐射的时间分布。利用密度泛函理论计算了一系列具有双光子激发和单光子电离潜力的有机化合物，并用N，N′-二甲基苯胺和乙腈测量了钛宝石激光器的二次和三次谐波发射脉冲宽度.这种方法有可能用于测量脉冲宽度短至1-3 fs的紫外区。
The temporal profile of the second and third harmonic emissions of a Ti:sapphire laser was measured using an autocorrelator consisting of a mass spectrometer as a two-photon-response detector. A number of organic compounds that are potentially applicable for two-photon excitation and subsequent one-photon ionization were investigated using density functional theory calculations.N,N′-dimethylaniline and acetonitrile were used for the measurement of the pulse width for the second and third harmonic emissions of the Ti:sapphire laser. This approach has the potential for use in measuring pulse widths as short as 1–3 fs in the ultraviolet region.
