Download or read book Tailoring Ultrashort Pulses for Surface Structuring and Characterizing Ultrashort Pulses written by Billy Lam (Optics scientist) and published by . This book was released on 2021 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: "This thesis is focused on the methods for tailoring ultrashort pulses for surface structuring and the methods for characterizing ultrashort pulses. In other words, the primary goal is to modulate as well as measure the spatio-temporal electric field E(x, y, t) = |E(x, y, t)|e i[phi](x,y,t) of an ultrashort pulse. Existing vector optical field (VOF) generators are either inefficient or require many optical elements with intensive alignment. I have demonstrated both a non-diffraction-based and a diffraction-based VOF-generator with a theoretical efficiency close to 100% using a spatial light modulator (SLM) to shape the focus of a femtosecond (fs) laser beam arbitrarily for surface structuring. Besides the beam focus, I have also fabricated curved laser-induced periodic surface structure (LIPSS) out-of-focus by controlling the polarization distribution of the beam. Both VOF-generators are compact with only a few optical elements and are easy to align for fs laser beams. These methods present an effective and energy-efficient way to shape the fs laser beam dynamically to create complex surface structures. For beam characterization, I have developed the wedged reversal shearing interferometer (WRSI), consisting of a single beam splitter cube (BSC), to retrieve the spatially resolved electric field E(x, y). The main advantages of the WRSI over existing techniques are its simplicity, stability, robustness, capability, and guaranteed zero-delay for ultrashort pulses. The WRSI can also be used together with a scanning Michelson interferometer, along with an additional temporal measurement using frequency-resolved optical gating (FROG), to measure the spatio-temporal field E(x, y, t). In addition, this thesis explores a new method to temporally characterize (E(t)) an ultrashort pulse with precise information on the carrier-envelope phase (CEP) in a single-shot operation. A feat unachievable by previous methods such as FROG and spectral phase interferometry for direct electric-field reconstruction (SPIDER), since spectrally resolved autocorrelation and spectral shear are insensitive to the CEP. The CEP is an important parameter of a few-cycle pulse because the CEP can vary from pulse to pulse and has a large impact on laser-matter interaction. The ability to measure the spectral phase and CEP of an arbitrary non-repeating ultrashort event is important for the study of ultrafast optical phenomena"--Pages xi-xii.

Available in PDF, EPUB and Kindle. Book excerpt: Bringing together contributions from leading experts in the field, this book reviews laser processing concepts that allow the structuring of material beyond optical limits, and methods that facilitate direct observation of the underlying mechanisms by exploring direct structuring and self-organization phenomena. The capacity to nanostructure material using ultrafast lasers lays the groundwork for the next generation of flexible and precise material processing tools. Rapid access to scales of 100 nm and below in two and three dimensions becomes a factor of paramount importance to engineer materials and to design innovative functions. To reflect the dynamic nature of the field at all levels from basic science to applications, the book is divided into three parts, Fundamental Processes, Concepts of Extreme Nanostructuring, and Applications, each of which is comprehensively covered. This book will be a useful resource for graduate students and researchers in laser processing, materials engineering, and nanoscience.

Download or read book Modeling Ultrashort Pulse Laser Damage with the Particle in Cell Method written by Alex Russell and published by . This book was released on 2019 with total page 148 pages. Available in PDF, EPUB and Kindle. Book excerpt: The precision and reproducibility of ultrashort pulse laser damage makes it amenable to a wide variety of applications, with a temporal separation between laser incidence and ablation of material resulting in a clean damage pattern that minimally affects the surrounding area. Additionally, as increasingly intense laser systems continue to be developed, the prevention or mitigation of laser damage becomes increasingly important. A number of numerical techniques have been developed for studying the dynamical processes involved, but each typically sacrifices either resolution on the atomic scale or the ability to model processes on the spatial scale of the laser. This work utilizes an ultrashort pulse laser damage algorithm built upon the framework of the particle-in-cell (PIC) method which is capable of resolving the complete damage process from laser incidence on the femtosecond scale to ablation and resolidification on the nanosecond scale. Moreover, it is capable of resolving the entire laser affected area while still capturing physics on the few nanometer scale. To prepare this algorithm for accurate application to real metals, I first modify a well established particle collision algorithm that kinetically evaluates short range deflections, enabling a PIC based laser target interaction to capture established material properties like absorption and skin depth without sacrificing the ability to model nonthermal velocity distributions and ballistic particles. With this advancement, the algorithm as a whole is validated by directly comparing copper craters experimentally produced over a range of fluences against craters produced via simulation with the same laser parameters. With experimental confirmation, the algorithm is then refined and expanded to allow better handling of physics like the quantum statistics affecting electron behavior during the laser target interaction and the influence of temperature on the nature of particle-particle interactions governing the ablation process. These advancements are then used to study the phenomena of laser induced periodic surface structure and the formation of transient warm dense matter produced by an ultrashort pulse on aluminum. Finally, I extend the applicability of the laser-target interaction portion of the algorithm to dielectrics by incorporating into it photoionization and impact ionization models appropriate for solid density materials. I then analyze the dynamics of these ionization processes in Zinc Selenide for pulses in the near-mid infrared regime.
