Examples of diatomic

• The remainder of the chapter introduces the reader to the theory of diatomic molecules in laser fields.

• The first two of these exist as diatomic gases at room temperature, and the latter two form diatomic vapors at moderately elevated temperatures.

• High harmonic generation in atomic and diatomic molecular gases using intense picosecond laser pulses-a comparison.

• This gives a relatively simple three-species gas mixture, of the type used in experimental facilities, which allows dissociation and recombination of the diatomic species.

• This result is similar to that for a diatomic molecular ion.

• This suggests that the fragment ions are ejected in opposite directions and the molecule behaves as a diatomic in the intense laser field.

• Of course, electron and ion collisions with diatomic molecules have not been considered, which would accelerate dissociation.

• However, no consideration is made for diatomic molecules.
