Many high intensity laser applications can generate large magnetic fields up to the level of 100’s of Tesla. In particular, the application of circularly polarized [1] or orbital angular mode (OAM) laser beams [2] can be used to generate such large fields using the inverse Faraday Effect (IFE). These fields can play an important role in the generation and guiding of electrons in laser plasma...

The efficient generation of MeV proton beams using lasers is an area of interest due to its potential applications, ranging from radiotherapy to the fast ignition concept for inertial confinement fusion. Various efficiency-enhancing schemes have been put forward, including using ultra-clean pulses with nm thick foils, and structured targets such as hemispheres to enhance fields. One method,...

637. Interferometric characterization of preplasma density for laser created plasmas

Poster (Student, In Competition) / Affiche (Étudiant(e), inscrit à la compétition)

High intensity laser plasma interactions are often affected by the preplasma created by leakage laser light (typically millijoules over nanoseconds) prior to the main high energy laser pulse (typically 100’s of joules). Even small amounts of preplasma can alter the absorption of laser light and creation of high energy electrons and ions in the interaction process. This can have significant...

861. Optical Pumping Within a Laser-Induced Plasma to Enhance Trace Element Signal Intensity

Poster (Student, Not in Competition) / Affiche (Étudiant(e), pas dans la compétition)

In the field of laser-induced breakdown spectroscopy (LIBS), it has been shown that trace elements can typically be detected at the parts per million level. However, to decrease the limit of detection further, there is a need to enhance the relatively small spectral lines of the trace elements. The technique of laser-induced fluorescence (LIF) is one of the best tools for providing this...

855. Terahertz source development for studying Warm Dense Matter and High Energy Density Plasmas

Chandra Curry (University of Alberta)

Plasma Physics / Physique des plasmas (DPP)

Poster (Student, Not in Competition) / Affiche (Étudiant(e), pas dans la compétition)

After decades of being referred to as the terahertz gap, terahertz radiation is now routinely used in spectroscopic and imaging applications. Further advancement, however, has been limited by the lack of high-energy sources. New studies indicating higher terahertz conversion efficiencies [1] open up the possibility of novel applications in high energy density physics. One such application...

868. Characterization of Initial Target Conditions in High Intensity Laser Solids Interaction Experiments

Plasma Physics / Physique des plasmas (DPP)

Poster (Non-Student) / affiche (non-étudiant)

Terawatt and Petawatt class high power laser systems have pre-pulses that can significantly affect the interaction physics. For example, in cone-guided high-intensity laser experiments the preformed plasma could cause filamentation and beam refraction [1]. Pre-pulses arrive picoseconds to nanoseconds before the main laser pulse can significantly increase the initial scale length and electron...
