“…A good fit of the spectra cannot be achieved without considering the contribution of the two absorption bands peaking at 2.16 and 2.61 eV, respectively, associated with the so-called inherent STHs. [11] Although these defects are known to be unstable at RT, Lancry and coworkers [26] found experimentally that STH precursors are present still at RT. Furthermore, recent studies have reported their generation in high-purity or fluorine-doped silica glasses, [27][28][29] even if their absorption bands are generally observed in bulk samples.…”

The transient radiation‐induced attenuation (RIA) of two different versions of pure‐silica‐core (PSC) multimode optical fibers (so‐called “solarization‐resistant” fibers) exposed to nanosecond 1 MeV X‐ray pulses are investigated. On‐line RIA spectra measurements at both room temperature (RT) and liquid nitrogen temperatures (LNT) in the range 1–3.5 eV are performed. Following the RIA kinetics, the properties of the metastable defects that are bleached just after the pulse are discussed. The spectral decomposition of the RIA is performed using known Gaussian bands associated to point defects absorbing in this spectral range. For both fiber types, the generation and the post‐irradiation kinetics of the self‐trapped holes (STHs) that are the main contributor to the transient RIA are investigated particularly. Moreover, thanks to the measurements performed at low temperatures the complex temperature dependence of the kinetics of self‐trapped holes and some chlorine‐related species is characterized.

“…This stood for a long time as the only example of a subwavelength structure in silica glass. Recently, fs laser‐induced nanostructures in other glasses have been reported: firstly, close to SiO 2 (e.g., doped silica), GeO 2 (a glass with an atomic arrangement close to SiO 2 ), TiO 2 ‐containing silicate glasses, and two multicomponent borosilicate glasses (with a few mol% of Na 2 O and Al 2 O 3 , BK7 (Schott), and Borofloat 33 (Schott) or alkali‐free aluminoborosilicate glass). For all of these, a similar nanostructure to the one observed in silica glass was described.…”

Nanoscale Phase Separation in Lithium Niobium Silicate Glass by Femtosecond Laser Irradiation

International audienceUnderstanding the phase transformation in glass and the morphology of related nanostructure after femtosecond laser irradiation is of great importance for fabricating functional optics, in which glass crystallization is involved to obtain nonlinear optical properties. We report on the crystallization inside lithium niobium silicate glass induced by fs laser irradiation. Energy-dispersive X-ray spectroscopy coupled to scanning transmission electron microscopy (STEM/EDS) and transmission electron microscopy confirm a nanoscale phase separation whereby LiNbO3 crystals are embedded in lamella-shaped frames of amorphous SiO2. The obtained nanostructure may have applications in fabricating second-order nonlinear optical devices

“…The femtosecond (fs) laser is a revolutionized material processing opening new avenues of the three dimensional (3D) photonic devices [1,2]. Fs laser driven self-organized nanostructures and nanovoids initially observed in fused silica related structural and optical properties that is studied extensively over one decade ago [1,2]. Subsequently, these sort of nanostructures are commonly known as "Nanogratings" consisting of sheet like cavities with a sub-wavelength periodicity and is successfully harnessed to scalable photonic applications including optofluidics and lab-on-a-chip devices [1][2][3][4][5][6].…”

Stress-induced optical waveguides written by an ultrafast laser in Nd³⁺, Y³⁺ co-doped SrF₂ crystals

High refractive index contrast, birefringence and luminescence properties of written channel waveguides inside fluoride crystals written by femtosecond (fs) laser have been studied. Herein, fs laser-induced stress affected zone is an efficient tool to create birefringence and high refractive index contrast in Nd 3+ , Y 3+ codoped SrF 2 crystal for wide range of pulse energies and repetition rates. In fabricating the waveguides at high repetition rate (typ. 500 kHz), we avoided too much heat accumulation, and thus they exhibit lower propagation loss in codoped SrF 2 crystal (1.63 ± 0.21 dB/cm for TM-polarization). The measured retardance can be interpreted as related to stress-induced birefringence in response to free of stress volume expansion photoinduced in the non-spherical irradiated zone. The photoluminescence and lifetime measurements are also carried out in order to understand local changes of the network in and around femtosecond laser induced waveguides written in codoped SrF 2 crystal.
