Three-dimensional photonic crystals (PCs) are periodic materials with a modulated refractive index on a length-scale close to the light wavelength. This optical property allows the design of optical components like highly reflective mirrors. Moreover

Photonic crystals are periodic materials with a modulated refractive index on a length scale close to the wavelength. We present the development of such photonic crystals with narrow-sized colloidal silica particles prepared by sol-gel process.

In this paper we examine how optical techniques can be used for impurities (or defects) detection and identification in KH 2 PO 4 (KDP) components. This is important in so far as some of these defects are responsible for a much weaker than expected L

In order to obtain optical surfaces of high quality in terms of roughness and cleanness, preparation of silica substrates requires specific processes. Particularly, polishing is one of the most critical stages of these processes. Indeed, fine abrasiv

In this work, rapidly grown KH2PO4 (KDP) crystals extracted from the prismatic and the pyramidal growth sectors of crystal boules were analyzed using photoluminescence measurements. From the spectra, we deduced a robust criterion to discriminate betw

In high power lasers, dielectric mirors have to fulfil drastic specifications in terms of reflexion and wavefront distortion. We present an optical thin film technology based on sol-gel process and called Laminar Flow Coating process.

This paper reports a study on correlation between stress field generated by extensive crystalline defects such as dislocation or growth boundaries and laser damage. It is found that stress fields decrease laser damage resistance. This result is compa

Previous work on KDP has shown that thermal annealing could improve laser damage resistance of KDP optics at 3w. However, the improvement varies with the pulse length: whereas a strong improvement was observed at 16ns, no improvement at all was obser

The rasterscan test procedure implemented in order to determine low laser damage density of large aperture UV fused silica optics was improved in terms of accuracy and repeatability. Tests have been carried on several facilities using several pulse d
