Engineering laser induced periodic surface structures on single crystal diamond (Conference Presentation)
Author(s): Ravi Shivaraman; Patrick S. Salter

Paper Abstract

Ultrashort pulses incident on diamond generates a modulating surface relief referred to as laser induced periodic surface structures. The present work demonstrates the ability to tune LIPSS geometry as well as its areal syntheses, through appropriate choice of fabrication parameters. Rigorous Coupled Wave Analysis of LIPSS derived 1D grating on single crystal diamond surface revealed an enhancement in optical transmission. Fine-tuning the process conditions to pattern such 1D gratings on diamond surface and demonstrating its efficacy opens a relatively cost-effective route to engineer highly transmissive optical elements from diamond.
