We demonstrate a passive Q-switched at 2 um region by integrating Bismuth (III) Telluride (Bi2/Te3) embedded in Polyvinyl Alcohol (PVA). Bi2Te3 was embedded in PVA by solution casting approach to develop a Bi2/Te3-PVA film and integrated in the laser cavity with ring configuration to generate pulse laser. The experimental works show that the proposed passive saturable absorber operates at input pump power ranges from 637 mW to 784 mW with central wavelength of 1957.6 nm. We observed the tunable repetition rate from 12.6 kHz to 26.1 kHz with the shortest pulse width of 2.22 us. The laser produces maximum instantaneous output peak power and pulse energy of 0.42 W and 0.94 uJ, respectively. Full Text: PDF ReferencesC. Zhao, H. Zhang, X. Qi, Y. Chen, Z. Wang, S. Wen, and D.

AbstractTransition metal dichalcogenides have been widely utilized as nonlinear optical materials for laser pulse generation applications. Herein, we study the nonlinear optical properties of a VS2-based optical device and its application as a new saturable absorber (SA) for high-power pulse generation. Few-layer VS2 nanosheets are deposited on the tapered region of a microfiber to form an SA device, which shows a modulation depth of 40.52%. After incorporating the microfiber-VS2 SA into an Er-doped fiber laser cavity, passively Q-switched pulse trains could be obtained with repetition rates varying from 95 to 233 kHz. Under the pump power of 890 mW, the largest output power and shortest pulse duration are measured to be 43 mW and 854 ns, respectively. The high signal-to-noise ratio of 60 dB confirms the excellent stability of the Q-switching state. To the best of our knolowdge, this is the first illustration of using VS2 as an SA. Our experimental results demonstrate that VS2 nanomaterials have a large potential for nonlinear optics applications.

An 1892.4 nm ultrafast passive Q-switched fiber laser is demonstrated by using Thulium-doped fiber (TDF) in conjunction with a multi-walled carbon nanotubes (MWCNTs) as a saturable absorber (SA). The MWCNTs film is sandwiched between two FC/PC fiber connectors and integrated into the laser cavity with 802 nm pump for Q-switching pulse generation. The pulse repetition rate can be tuned from 3.8 to 4.6 kHz while the corresponding pulse width reduces from 22.1 to 18.4 μs as the pump power is increased from 187.3 to 194.2 mW. A higher performance Q-switched Thulium-doped fiber laser (TDFL) is expected to be achieved with the optimization of the MWCNT-SA saturable absorber and laser cavity.
