Spatial chirp control of high-intensity 4D pulse focusing for laser-matter interactions
Center for Microintegrated Optics for Advanced Bioimaging and Control Department of Physics Colorado School of Mines Golden, CO, USA 80401
Spatial chirp can be manipulated to control the focusing conditions for materials processing. Our double-ABCD nonparaxial analysis helps to understand and exploit the mechanisms for intensity localization, pulse front tilt, and grating formation, and includes initial spectral phase and detuning of the wavelength crossing plane. We also present a novel method for creating high density, high intensity interference patterns with crossed beams that have no relative pulse front tilt.
