“…To control the number of pulses in each burst, an acousto-optic modulator (AOM) is used to select groups of seed pulses from the 50 MHz pulse train from ytterbium-doped fiber laser [12]. The burst pulse was generated in an ytterbium-doped double-clad fiber (YDF) using a small length of samarium-doped fiber as a saturable absorber [13]. The burst pulse output was obtained in allpolarization maintaining ytterbium-doped fiber using nonlinear amplifying loop mirror with the figure-eight configuration [14].…”

We experimentally demonstrate the unconventional burst-pulse bundle generation in a linear-cavity ytterbium-doped double-clad fiber laser based on self-mode-locked and double passively-Q-switched technologies. When the pump power is 4421.0 mW, we obtained the burst pulse bundle with proportional pulse qualities. The full width at half maximum (FWHM) of the burst pulse is 2.2 μs, the time interval between the adjacent burst pulse is 2.4 μs and the energy of a single burst pulse is 0.62 μJ. In addition, the maximum burst-pulse energy is 0.85 μJ at the pump power of 4574.0 mW, the minimum FWHM and time interval are 1.7 and 1.4 μs at the pump power of 5387.0 mW. The formation mechanism of the unconventional burst pulse bundle is also discussed in detail.

“…Previously, rare-earth oxide (REO) had also been manipulated as SA in near-infrared pulsed laser generation (1-2 µm) [25,26]. Das et al [27] demonstrated Samarium-doped fiber as SA for ytterbium-doped fiber lasers which successfully generated pulses in the 1 µm range. With a fast response time of 5 ns, Samarium oxide (Sm2O3) has excellent nonlinear absorption ability of 33% in a 1.5 µm regime [28,29].…”

The rapid developments in transition metal dichalcogenide materials as a saturable absorber (SAs) have been demonstrated to be an effective method for generating Q-switched fiber laser. This work, reports on the generation of Q-switched fiber laser in the 1-micron region using samarium oxide (Sm2O3) saturable absorber (SA).

In this paper, we report on the use of samarium oxide (Sm2O3) saturable absorber (SA) for 1-micron Q-switched fiber laser generation. The Sm2O3 thin film SA was constructed in-house through which the Sm2O3 powder was mixed and stirred in polyvinyl alcohol (PVA) solution. It was then integrated into the ytterbium-doped fiber laser (YDFL) ring cavity, hence producing a sequence of Q-switched pulsed lasers at 1062.49 nm wavelength. The stable pulse train appeared from 69.97 to 111.1 kHz between the applied pump power of 57 mW to 96 mW. The signal-to-noise ratio (SNR) of 38.56 dB was recorded at the 57 mW pump power, whereas the pulse energy raised until 15.21 nJ at 96 mW. These results showed that the Sm2O3 could be a favourable SA material to iniatiate Q-switched ytterbium-doped pulsed fiber laser. ABSTRAK: Perkembangan pesat dalam bahan logam peralihan dichalcogenide sebagai bahan penyerap boleh larut (SAs) telah dilaporkan sebagai kaedah yang berkesan bagi menjana laser fiber Q-switched. Kajian ini menggunakan samarium oksida (Sm2O3) saturable absorber (SA) bagi menjana laser gentian Q-switched 1-Micron. Filem nipis Sm2O3 SA telah dihasilkan melalui campuran serbuk Sm2O3 ke dalam cecair polivinil alkohol (PVA) dalam persekitaran makmal. Kemudian, ia diintegrasi ke dalam rongga gelang laser gentian dop-ytterbium (YDFL), lalu menghasilkan denyut laser Q-switched stabil pada jarak gelombang 1062.49 nm. Denyutan stabil muncul dari 69.97 kepada 111.1 kHz pada kuasa pam yang dikenakan antara 57 mW hingga 96 mW. Nisbah isyarat-hinggar (SNR) pada 38.56 dB telah direkodkan pada pam kuasa 57 mW, sementara denyut tenaga ditingkatkan kepada 15.21 nJ pada 96 mW.

It was integrated into the ytterbium-doped fiber laser (YDFL) ring cavity, hence producing a stable passively Q-switched laser operating at 1062.49 nm wavelength. Stable pulse train appeared from 69.97 to 111.1 kHz at the tunable pump power of 57 mW to 96 mW. The pulse energy of up to 15.21 nJ and signal-to-noise ratio (SNR) of 38.56 dB for the fundamental frequency were recorded. The results showed that the Sm2O3 could be a favourable SA material for the broadband generation of Q-switched fiber laser.

“…In fact, various fiber SAs have been developed for the Q-switching of YDFLs, including Tm-doped fiber SA [10], Sm-doped fiber SA [11][12][13], Cr-doped fiber SA [14] and Ho-doped fiber SA [15]. Even YDF itself is exploited as a fiber SA to Q-switch YDFLs using the mode field area mismatch technique [16][17][18].…”

A theoretical model concerning a pulsed, single cavity Yb-Bi fiber laser is established. A Q-switching rate equation is derived for mode field area mismatch operations. A stable Q-switching wavelength range and corresponding pump range of this laser system is explored, and the detailed population transition processes are described. Further, the pulse characteristics of the laser system are investigated with different pump powers at 1120 nm. The simulations show that, for a single cavity Yb-Bi fiber laser, stable passive Q-switching could be attained in a relatively wide wavelength range, and a relatively larger coupling ratio is more favorable for laser design. At a fixed wavelength, a steady region-where the pulse energy, peak power and pulse duration show little variation with the change of the pump powerexists, and the main cause is the relatively steady effective pump energy in this region.
