Diamond machining of a single shot ellipsoidal focusing plasma mirror (2016)
Presentation / Conference Contribution
Bourgenot, C., Crosby, D., & Robertson, D. (2017, January). Diamond machining of a single shot ellipsoidal focusing plasma mirror. Presented at Optics and Measurement International Conference 2016, Liberec

Plasma mirrors have become an important tool in high power laser physics due to their ability to suppress laser pre-pulses and amplified spontaneous emission allowing a cleaner and sharper rising edge pulse to be focused onto a target. A PMMA ellipso... Read More about Diamond machining of a single shot ellipsoidal focusing plasma mirror.

Towards freeform curved blazed gratings using diamond machining (2016)
Presentation / Conference Contribution
Bourgenot, C., Robertson, D., Stelter, D., & Eikenberry, S. (2016, October). Towards freeform curved blazed gratings using diamond machining. Presented at Advances in Optical and Mechanical Technologies for Telescopes and Instrumentation II, Edinburgh, Scotland

Concave blazed gratings greatly simplify the architecture of spectrographs by reducing the number of optical components. The production of these gratings using diamond-machining offers practically no limits in the design of the grating substrate shap...

Resolution limits of pixellated optical components (2016)
Presentation / Conference Contribution
Cowie, E. N., Bourgenot, C., Robertson, D., & Courtial, J. (2016, December). Resolution limits of pixellated optical components. Presented at Novel Optical Systems Design and Optimization XIX, San Diego, California

Pixellated optical components, for example generalised confocal lenslet arrays (GCLAs), enable the design of optical devices which cannot be realised without introducing pixellation or a similar compromise. A key concern is the degradation of imaging... Read More about Resolution limits of pixellated optical components.

CHOUGH: implementation and performance of a high-order 4m AO demonstrator (2016)
Presentation / Conference Contribution
Bharmal, N. A., Basden, A. G., Bourgenot, C. J., Black, M., Dubbeldam, C. M., Henry, D. M., Hölck-Santibanez, D., Morris, T. J., Robertson, D. J., Schmoll, J., Talbot, R. G., Younger, E. J., & Myers, R. M. (2016, July). CHOUGH: implementation and performance of a high-order 4m AO demonstrator. Presented at Adaptive Optics Systems V, Edinburgh

CHOUGH is a small, fast project to provide an experimental on-sky high-order SCAO capability to the 4.2m WHT telescope. The basic goal has r0-sized sub- apertures with the aim of achieving high-Strehl ratios (> 0:5) in the visible (> 650 nm). It achi...
