Spectroscopy is a key technique in astronomy and nowadays most major telescopes include at least one spectrograph in their instrument suite. The dispersive element is one of the most important components and it defines the pupil size, spectral resolu...

Development of Focusing Plasma Mirrors for Ultraintense Laser-Driven Particle and Radiation Sources (2018)
Journal Article
Wilson, R., King, M., Gray, R., Carroll, D., Dance, R., Butler, N., …McKenna, P. (2018). Development of Focusing Plasma Mirrors for Ultraintense Laser-Driven Particle and Radiation Sources. Quantum Beam Science, 2(1), Article 1. https://doi.org/10.3390/qubs2010001

Increasing the peak intensity to which high power laser pulses are focused can open up new regimes of laser-plasma interactions, resulting in the acceleration of ions to higher energies and more efficient generation of energetic photons. Low f-number... Read More about Development of Focusing Plasma Mirrors for Ultraintense Laser-Driven Particle and Radiation Sources.
