Nanomaterials with remarkable optical, mechanical, and electrical properties have shed new light on various fields including optoelectronics, sensors, biomedicine, and ultrafast photonics. Particularly, owing to their nonlinear optical properties, fast recovery time, and broadband operation, nanomaterials are well qualified as saturable absorbers in ultrafast pulsed lasers. Over the development of the past decades, various nanomaterials have been developed as saturable absorbers, which contribute to a diversity of lasers with excellent performance. Therefore, it is important for researchers to provide a landmark of the applications of nanomaterials in ultrafast photonics concerning cutting‐edge development. Herein, the integration and applications of nanomaterials in ultrafast photonics are reviewed. First, end‐face, lateral, as well as photonic crystal fibers padding integration methods are introduced along with their process and characteristics. Then the ultrafast applications of nanomaterials including carbon‐based (carbon nanotubes and graphene), typical 2D (topological insulators, transition metal dichalcogenides, black phosphorus, and MXenes), and metal‐based nanomaterials (gold, silver, copper, and metal oxides) are summarized. Major parameters of ultrafast lasers and features of each nanomaterial are presented simultaneously. Finally, the perspectives of nanomaterials for further development in ultrafast photonics are discussed.

“…On the other hand, lasing in a 2 µm wavelength regime can be achieved by a thulium-doped fiber laser (TDFL) or a thulium-holmium-doped fiber laser (THDFL). [11,12] These lasers operate at a wavelength range of around 1.7 µm-2.2 µm, which is an eye-safe region. [13] As there is reasonable water absorption in this region and some gas molecules such as carbon dioxide are present in the environment, there will be strong absorption occurring at 2 µm.…”

In this work, we have demonstrated antimonene as a saturable absorber to generate ultrafast mode-locked and Q-switched laser at a 2-micron wavelength region. The two antimonene-based SAs were prepared and inserted separately in a thulium-holmium doped fiber laser (THDFL) to produce the pulsed lasers. Antimonene was coated onto the tapered fiber to generate soliton mode-locked pulses and in thin-film form for the generation of Q-switched pulses. The modelocking was stable within the pump power of 267 to 511 mW, and the laser operated at the center wavelength of 1897.4 nm. The mode-locked laser had a pulse width of 1.3 ps and a repetition rate of 12.6 MHz, with a signal-to-noise ratio (SNR) of 64 dB. The Q-switched laser operation was stable at the wavelength of 1890.1 nm within the pump power of 312 to 381 mW. With the increase in pump power from 312 mW to 381 mW, the repetition rate increased to a maximum of 56.63 kHz and the pulse width decreased to a minimum value of 2.85 μs. A wide range tunability of Q-switched laser was also realized within the wavelength of 1882 to 1936 nm.

“…Particularly, in the exploration of novel nanomaterials with suitable properties for optical applications, titanium nitride (TiN) has been demonstrated as an attractive plasmonic possessing nonlinear optical properties in the near-infrared (NIR) wavelength range [14]. Additionally, titanium dioxide (TiO 2 ) has been demonstrated as an oxide semiconductor and insulator with nonlinear absorption for its use as a SA element in the NIR region [15]. In this regard, a number of compositions, called in general titanium oxynitrides (TiO x N y ), are obtained as a result of different intermediate phases between TiN and TiO 2 .…”

TiOxNy Thin Film Sputtered on a Fiber Ball Lens as Saturable Absorber for Passive Q-Switched Generation of a Single-Tunable/Dual-Wavelength Er-Yb Double Clad Fiber Laser

et al. 2020

View full text Add to dashboard Cite

The use of titanium oxynitride (TiOxNy) thin films as a saturable absorber (SA) element for generation of passive Q-switched (PQS) laser pulses, from a linear cavity Er-Yb double-clad fiber (EYDCF) laser, is demonstrated. Additionally, the deposition of the material as a thin film covering a fiber micro-ball lens (MBL) structure is reported for the first time. The TiOxNy coating is deposited by a direct current (DC) magnetron-sputtering technique. The MBL is inserted within the laser cavity in a reflection configuration, alongside a reflecting mirror. As a result, the coated fiber MBL simultaneously acts as a SA element for PQS laser pulses generation and as an interference filter for wavelength selection and tuning of the generated laser line. Tunable single-laser emission in a wavelength range limited by dual-wavelength laser generation at 1541.96 and 1547.04 nm is obtained. PQS laser pulses with a repetition rate from 18.67 to 124.04 kHz, minimum pulse duration of 3.57 µs, maximum peak power of 0.359 W, and pulse energy of 1.28 µJ were obtained in a pump power range from 1 to 1.712 W.
