2022年11月14日 · Heath Bigman grew up in the small community of Shiprock New Mexico in the Navajo Nation that spans three states over the four corners region of New Mexico, Arizona and Utah. Bigman double majored in physics and chemistry for his undergrad and went on to obtain a master’s in physics from San Diego State University with an emphasis in lasers.

HAPLS set a world record for diode-pumped petawatt lasers, with energy reaching 16 joules (J) and a 28 femtosecond (fs) pulse duration (equivalent to ~0.5 petawatt/pulse) at a 3.3 hertz (Hz) repetition rate (3.3 times per second). In just three years, HAPLS went from concept to a fully integrated and record-breaking product.

2012年2月8日 · In this paper, we present a unique approach for generating ultrabroadband optical vortices using two passes off a single segmented SLM, and measur-ing their charge using the triangular aperture technique. 2. VORTEX GENERATION. The essential element in generating an optical vortex is the now familiar spiral phase plate.

Heath Bigman is a Laser System Engineer at Lawrence Livermore National Laboratory based in Livermore, California. Previously, Heath was a Senior S ystem Test Engineer at ASML and also held positions at ASML.

In this Letter, we demonstrate the measurement of vortex charge via this approach for vortex beams up to charge ±7. We also demonstrate the use of this technique for measuring femtosecond vortices and noninteger vortices, comparing these results with numerical modeling.
