Dynamic control of population inversion and high harmonic generation in semiconductors using chirped laser pulses

Lu Liu, Yindong Huang, Jing Zhao

Population inversion is essential for efficient laser generation. Traditional methods for semiconductor lasers, such as direct current injection and optical pumping, face challenges in achieving precise control. In this study, we introduce an approach using chirped laser fields to dynamically realize population …

Colorimetric Characterization of Color Imaging System Based on Kernel Partial Least Squares

Siyu Zhao, Lu Liu, Zibing Feng, Ningfang Liao et autres

Colorimetric characterization is the basis of color information management in color imaging systems. In this paper, we propose a colorimetric characterization method based on kernel partial least squares (KPLS) for color imaging systems. This method takes the kernel function expansion of the …

Asymmetry in high-order harmonic generation of polar molecule CO

Yan Yang, Bin Zhang, Zhongxue Ren, Guang-Ru Bai et autres

Compared with nonpolar molecules, owing to the inherent asymmetry, polar molecules exhibit rich and very complex electronic dynamics under the interaction with strong laser fields. In this work, high-order harmonic generation (HHG) of polar molecules CO is investigated by using the three-dimensional …

Effect of ionization asymmetry on high harmonic generation from oriented CO in orthogonal two-color fields

Yan Yang, Lu Liu, Jing Zhao, Yanyun Tu et autres

Abstract We investigate the high harmonic generation from oriented CO molecules in orthogonal two-color (OTC) fields by solving the three-dimensional time-dependent Hartree–Fock equation. The infrared fundamental laser pulse with frequency ω polarized along the molecular axis drives the harmonic generation process, while …
