“…As the spectral response of gold nanorods covers a broad spectral region in the infrared region, it is easy to extend the operating wavelength of such noble metal NP based optical switches to drive mode-locking pulse output in fiber lasers based on, e. g., Yb-doped fiber at 1.0 µm (Kang et al, 2014), and Tmdoped fiber at 2.0 µm (Kang et al, 2015). On the other hand, the geometrical anisotropy of gold nanorods provides another dimension to modulate pulse generation in fiber lasers.…”

Light-matter interactions are greatly enhanced and spatially well-confined in plasmonic nanostructures in the spectral resonance range. In colloidal plasmonic nanoparticle (NP), this effect is manifested by the strong absorption caused by the collective oscillation of conduction electrons in NPs, known as the localized surface plasmon resonance (LSPR). The strong spectral resonance due to LSPR also contributes to the large enhancement in optical nonlinearity, such as nonlinear absorption and optical Kerr effect, and the ultrafast transient photo-bleaching in those materials making them ideal platforms for exploring optical switching behavior that is needed in all optical devices. Here, we review the recent advances in the use of colloidal processed noble metal, metalloid, chalcogenide and oxide plasmonic NPs for ultrafast optical switches to drive pulse laser generation in both solid state and fiber lasers. The broadband and ultrafast response of these plasmonic NPs offers a significant advantage in devices performance and allows the pulse generation from near infrared (NIR) to middle infrared (MIR) spectral range with pulse duration down to 100-femtosecond level. Compared with commercial products and other optical switches based on 2D materials, these plasmonic NPs are expected to provide a competitive and cost-efficient material solution to compact ultrafast pulse lasers and relevant devices.

The International Year of Light 2015 was a landmark for the laser and optics community pointing the way to a bright future for humanity and the environment. It is with great satisfaction that Laser Physics and Laser Physics Letters have published many notable articles that have contributed to the development of light-based technologies and breakthroughs in photonics. In recognition of their high quality, we present a selection of some of the most popular articles published by Laser Physics and Laser Physics Letters throughout 2015, all of which are believed to have the potential to make a high impact on future research directions. Those chosen are recognised for their high-interest with readers and importance in the field, providing a snapshot of the broad subject coverage and international make-up of both journals.Starting this year, we will be recognising and announcing annual highlights of a previous year for both journals.

“…The outstanding properties of the metal nanoparticles have been promoting the interesting applications in the areas of optics, medicine, and spectroscopy [36][37][38][39][40][41]. It is worthy to note that metal nanoparticles have exhibited great potential in the application of ultrafast fiber lasers as SAs for Q-switched and mode-locked pulse generation [42][43][44][45][46][47][48][49][50]. Up to now, most metal nanoparticles-based SAs researches focus on Au nanoparticles as SAs for achieving Q-switching or mode-locking, implemented in the major fiber lasers (i.e.…”

We report on a Q-switched Yb-doped all-fiber laser based on a solution-processed Ag nanoplates saturable absorber. Optical deposition procedure is implemented to transfer the Ag nanoplates onto the fiber core area through the thermal effect. The saturable absorber is sandwiched between two fiber connectors, providing simplicity, flexibility, and easy integration into the laser oscillator. The modulation depth and saturation incident fluence are measured to be ~5.8% and ~106.36 μJ/cm2 at 1-μm region, respectively. Self-started stable Q-switched operation is achieved for a threshold pump power of 180 mW. The repetition rates of the pulse trains range from 66.6 to 184.8 kHz when the pump power scales from 210 to 600 mW. The maximum average output power is 10.77 mW, corresponding to the single-pulse energy of 58.3 nJ and minimum pulse duration of ~1.01 μs. To the best of our knowledge, it is the first time that the Ag nanoplates saturable absorbers are utilized in the 1-μm Yb-doped Q-switched fiber laser.
