“…Saturable absortion is attributed to the ground state bleaching at relatively low intensities and, RSA at high excitation intensities is ascribed to the cumulative effect of ESA, two photon absorption and nonlinear scattering. The intensity dependent switching behavior attributed by SA and RSA of noble metal nanoparticles can be possibly utilized for variety of photonic applications like optical pulse compression, mode locking, all-optical switching and optical power limiter (Gurudas et al 2008;1986;Ganeev et al , 2009Kiran et al 2004;Wang et al 2010). …”

Silver nano-colloid was prepared by chemical reduction method and its nonlinear absorption properties were investigated by using open aperture z-scan experiment with nanosecond laser pulses operating at 532 nm. Interestingly, a switch over from saturable absorption to reverse saturable absorption was observed when the input intensity is increased from 28.1 to 175.8 MW/cm 2 . The underlying mechanism responsible for the observed switching behaviour is the interplay between ground state plasmon band bleaching and excited state absorption. Theoretical fitting was done by using a model in which nonlinear absorption coefficient as well as saturation intensity are incorporated.

“…The most intriguing aspect is that the LSPR effect can significantly enhance optical nonlinearity without sacrificing the ultrafast response . Utilizing this property, noble metals NCs have been used as saturable absorbers (SAs) and applied for both mode‐locking and Q‐switching pulse generation . However, for most of traditional noble metals, the plasmonic nonlinearity in the infrared region, especially in the telecommunication bands, is relatively low, which is the major reason for limited development of pulsed lasers based on plasmonic metal NCs.…”

“…However, for most of traditional noble metals, the plasmonic nonlinearity in the infrared region, especially in the telecommunication bands, is relatively low, which is the major reason for limited development of pulsed lasers based on plasmonic metal NCs. [26e] Apparently, heavily doped copper‐based NCs offer higher LSPR tunability in the NIR region and much better compatibility, which would be promising alternatives used in laser‐based telecommunication. Nevertheless, up to now, the use of LSPR effect of solution‐processed copper‐based NCs in pulsed lasers working in infrared wavebands, especially in the telecommunication range of around 1.5 μm, is yet to be demonstrated.…”

A new approach to synthesize self-doped colloidal Cu3-x P NCs with controlled size and localized surface plasmon resonance absorption is reported. These Cu3-x P NCs show ultrafast exciton dynamics and huge optical nonlinearities due to plasmonic resonances, which afford the first demonstration of plasmonic Cu3-x P NCs as simple, effective, and solution-processed nonlinear absorbers for high-energy Q-switched fiber laser.

“…It is worth noting that the glass dispersed with Pt NPs behaves stronger with nonlinear absorption (Im χ (3) = −2.23 × 10 −10 esu) comparing with nonlinear refraction (Re χ (3) = 1.23 × 10 −11 esu) in magnitude. This phenomenon is also noteworthy for Pt NPs suspensions at varied wavelengths, e.g., at 792 nm of 120 fs, 1064 nm of 50 ps, and 800 nm with femtosecond pules . In regard of narrow interval band structure of Pt NPs as discussed above, Fan and his co‐workers interpreted the underlying mechanism for prominent saturable absorption as interband electron transition by monophoton absorption .…”

Silica glasses dispersed with Pt nanoparticles and Ag nanoparticles are derived from solid‐state sintering of mesoporous silica SBA‐15 encapsulated with Pt nanoparticles and Ag nanoparticles, respectively. Using mesoporous powders for sintering is a facile method to lower synthesis temperature for glass making and to efficiently disperse noble metal nanoparticles in silica glass matrix. The included nanoparticles still play their functional roles in impacting on optical properties of the glass products prepared by this novel method. The glass dispersed with Pt nanoparticles exhibits brown color due to the interband electron transition of Pt nanoparticles. The coloring effect of surface plasmon resonance absorption from Ag nanoparticles colors the glass dispersed with Ag nanoparticles with yellow. Open‐aperture and closed‐aperture Z‐scan methods are applied to measure third‐order nonlinear absorption and refraction coefficient of the composite glasses, respectively, under femtosecond laser radiation at 880 nm wavelength. The glass dispersed with Pt nanoparticles behaves intense nonlinear absorption comparing with nonlinear refraction in magnitude, which could be attributed to interband electron transition by monophoton absorption of Pt nanoparticles. The glass dispersed with Ag nanoparticles shows stronger nonlinear refraction than saturated absorption. The dominant contribution to third‐order optical nonlinearity of silica glass dispersed with Ag nanoparticles is intraband transition of free electrons near the Fermi surface of Ag nanoparticles. This method may have potential applications for fabricating silica glasses dispersed with ultrafine functional particles, which are potentially applicative in the fields of photonics.
