摘要: Abstract The interaction of thiazole and thiazolidine with a strong (∼ 2×10 16 W/cm 2 ) fs laser field has been studied at λ=790 nm by means time-of-flight (TOF) mass spectrometry. observed relative abundance the doubly charged intact parent ion in is higher than that thiazole, while laser-molecule coupling strength found to be much more efficient for aromatic (thiazole) nonaromatic (thiazolidine) molecule. spectra are attributed combination ionization subsequent multiphoton processes. It also concluded, direct Coulomb explosion within transient multiply ions leads production atomic ions.
