“…Zhan and co-workers reported the efficient synthesis of graphene embedded in sol-gel Ormosil glasses. [376,377] They used both nanosheets (GONSs) and nanoribbons (GONRs) (Figure 32). The prepared materials showed high linear transmission in the visible, good thermostability and good optical limiting response attributed to both nonlinear scattering and nonlinear absorption.…”

Research on hybrid inorganic‐organic materials has experienced an explosive growth since the 1980s, with the expansion of soft inorganic chemistry based processes. Indeed, mild synthetic conditions, low processing temperatures provided by “chimie douce” and the versatility of the colloidal state allow for the mixing of the organic and inorganic components at the nanometer scale in virtually any ratio to produce the so called hybrid materials. Today a high degree of control over both composition and nanostructure of these hybrids can be achieved allowing tunable structure‐property relationships. This, in turn, makes it possible to tailor and fine‐tune many properties (mechanical, optical, electronic, thermal, chemical…) in very broad ranges, and to design specific multifunctional systems for applications. In particular, the field of “Hybrid‐Optics” has been very productive not only scientifically but also in terms of applications. Indeed, numerous optical devices based on hybrids are already in, or very close, to the market. This review describes most of the recent advances performed in this field. Emphasis will be given to luminescent, photochromic, NLO and plasmonic properties. As an outlook we show that the controlled coupling between plasmonics and luminescence is opening a land of opportunities in the field of “Hybrid‐Optics”.

“…63 To investigate materials with significant nonlinear scattering, the Z-scan has been augmented by placing a secondary detector off-axis. 37,64 Consider also, in measurements of nonlinearly scattered radiation, that the scattering might not be spherically homogenous. 65 For certain materials, an integrating sphere intensity scanning measurement is preferable.…”

“…A stringent definition of damage is that no decrease of transmission is detected during several pulses on the same spot while also finding no damage in microscopy images. 37 This method is preferable for separating RSA from damage mechanisms. Other methods include photophysical measurements indicating RSA and ensuring that the nonlinear scattering from glass damage is low.…”

“…30 The solubility of chromophores and the dispersion ability of nanoparticles are vital properties in the preparation of doped glasses. 24,30,[33][34][35][36][37] For MTEOS glasses, it is possible to control cavity size, i.e., tuning the exposure of the chromophores to oxygen quenching. 30 Recent work in the OPL research field includes efforts to increase the span of pulse lengths and the range of wavelength response.…”

How to assess good candidate molecules for self-activated optical power limiting

et al. 2018

Abstract. Reverse saturable absorbers have shown great potential to attenuate laser radiation. Good candidate molecules and various particles have successfully been incorporated into different glass matrices, enabling the creation of self-activated filters against damaging laser radiation. Although the performance of such filters has been impressive, work is still ongoing to improve the performance in a wider range of wavelengths and pulse widths. The purpose of this tutorial is, from an optical engineering perspective, to give an understanding of the strengths and weaknesses of this class of smart materials, how relevant photophysical parameters are measured and influence system performance and comment on the pitfalls in experimental evaluation of materials. A numerical population model in combination with simple physical formulas is used to demonstrate system behavior from a performance standpoint. Geometrical reasoning shows the advantage of reverse saturable absorption over nonlinear scattering due to a fraction of scattered light being recollected by imaging system optics. The numerical population model illustrates the importance of the optical power limiting performance during the leading edge of a nanosecond pulse, which is most strongly influenced by changes in the two-photon absorption cross section and the triplet linear absorption cross section for a modeled Pt-acetylide. This tutorial not only targets optical engineers evaluating reverse saturable absorbing materials but also aims to assist researchers with a chemistry background working on optical power limiting materials. We also present photophysical data for a series of coumarins that can be useful for the determination of quantum yields and two-photon cross sections and show examples of characterization of molecules with excited triplet states.

“…In previous reports, Zheng et al made the gold nano-particles/GO into Ormosil glasses by physical mixture of silane sol-gel and gold nano-particles/GO composites and found these glasses have nonlinear absorption and scattering effects under a 532 nm laser [21]. Zhan prepared GO Ormosil glasses at 0.03% by mixing GO with silane sol and found that they have nonlinear absorption and scattering under nanosecond and picosecond pulse lasers [24,25]. These works have obviously confirmed that graphene or GOs could be composited into sol-gel matrix by physical mixture.…”

A class of graphene oxide (GO) Ormosil glasses with excellent nonlinear optical properties were made with sol-gel method. The as-prepared GO Ormosil glasses were highly transparent in visible and near-infrared region, due to the uniform dispersion of modified GO in the matrix. These Ormosil glasses have a broadband optical limiting effect from 532 to 1570 nm, with lower optical limiting onset energy density (F ON ). The nonlinear absorption coefficients of the Ormosil glass could reach 210.62, 647.96, and 43.10 cm GW −1 at 532, 1064, and 1570 nm. The optical limiting properties of the Ormosil glasses come from nonlinear absorption proved by Z-scan measurements. Therefore, the Ormosil glasses have potential applications in nonlinear optical areas.
