Abstract

Understanding the interaction between strong laser field and energetic molecules is an important task for practical implementation of the laser-induced ignition for high energy propulsion applications. One of the generic consequences of the interaction of a strong laser field with molecules is high harmonic generation (HHG). Thus far, high harmonic generation has not been observed from any energetic molecule. The purpose of this paper is to present an HHG spectrum obtained for a simple energetic molecule, nitromethane, at various gas cell pressures and laser beam intensities. The experimental spectrum is compared and contrasted with the theoretical one obtained under the approximation of single active electron in molecular electrostatic potential. We believe that the present work would open door to the further investigation of the laser ignition chemistry of energetic molecules from an HHG point of view. © 2022
