A New Generation of Ultrafast Oscillators for Mid-Infrared Applications

This thesis presents the first successful realization of a compact, low-noise, and few-cycle light source in the mid-infrared wavelength region. It achieves this by pumping femtosecond chromium-doped II-VI laser oscillators directly with the emission of broad-stripe single-emitter laser diodes, resulting in coherent light with exceptionally low amplitude noise. The oscillator's output parameters, such as pulse duration and power, match and even surpass previous state-of-the-art systems. A demonstration of its unique capabilities is shown by driving the nonlinear generation of coherent mid-infrared light spanning multiple octaves. The thesis comprehensively documents the technology's development and provides a valuable reference for constructing a new generation of mid-infrared light sources.

This thesis presents a groundbreaking achievement in the realm of mid-infrared light sources by successfully realizing a compact, low-noise, and few-cycle light source. Through the development of a novel pumping technique, femtosecond chromium-doped II-VI laser oscillators were directly driven by the emission of broad-stripe single-emitter laser diodes, resulting in coherent light with remarkably low amplitude noise. This breakthrough is of paramount importance for a wide range of applications, including high-sensitivity spectroscopy. Notably, the oscillator's output parameters, including pulse duration and power, surpassed previous state-of-the-art systems. To showcase its unique capabilities, the oscillator's powerful output was employed to drive the nonlinear generation of coherent mid-infrared light spanning multiple octaves, demonstrating the system's exceptional brilliance and ultrabroad spectral bandwidth.

The comprehensive development of this technology is meticulously documented in this PhD thesis. It includes a thorough review of literature and applications, as well as an in-depth analysis of the theoretical foundations behind ultrafast laser oscillators. This thesis serves as a valuable resource for constructing a new generation of mid-infrared light sources, paving the way for innovative applications in various fields.
