When the electric field of a laser pulse approaches the field strength between a nucleus and valence electron, it is capable of ionizing atoms or molecules via quantum tunneling. Additionally, the laser field can turn and accelerate the electron to c

This thesis examines plasmas generated by and interacting with short pulse lasers (1), with a particular focus on plasmas generated from initially ultrathin (10^21 W/cm^2) are incident on the target. To improve the pre-pulse contrast, self-triggering

Ultra-Fast Scanning Tunneling Microscopy (UFSTM) is a novel imaging technique that uses high intensity femtosecond laser light to generate atomic defect states called "traps" and provide subsequent atomic surface imaging between pulses. Many surface

In this thesis, we lay the groundwork for performing attosecond transient absorption spectroscopy (ATAS) measurements in the condensed phase using mid-infrared (MIR) lasers. This was accomplished by designing, building and testing several pieces of h

Advancements in spintronics rely on materials which exhibit stable magnetization or long-lived spin states that can be easily manipulated or probed. One class of two-dimensional (2D) materials, the monolayer transition metal dichalcogenides (TMDs) ha

Fundamental properties of mixed states of light and matter were studied. Mixed states of surface plasmon polaritons (SPP) and the holes of mesh, treated as etalons, are called cavity mediated SPPs herein. This work presents the narrowest measured cav

This thesis explores the interaction of pulsed lasers with plasmas in the relativistic regime, i.e. when the kinetic energy of electrons in the laser field exceeds mc². Plasmas in such conditions can be created in the laboratory using petawatt class

Like many problems in physics, the interaction between high intensity laser pulses and solid materials depends critically on the relative timescales of the drive (the laser pulse with finite duration) and the material response. This is especially tru

Light-matter interactions are key in providing fundamental information about materials. The terahertz (THz) frequency range is a critically important region of the electromagnetic spectrum where the electronic properties of many quantum materials hav

Counterfeit pharmaceuticals kill around 1 million people per year. While nations can decrease the danger posed to their citizens by instituting standards and institutional safeguards on pharmaceutical importation and production, presently there is no
