“…F IBER saturable absorbers (FSAs) have been widely studied for passive Q-switching of various rare earth doped fiber lasers [1]- [4]. As absorption bands of Tm ions overlap with the emission bands of Yb-doped fiber laser and Er-doped fiber laser [5], Tm-doped fiber and Tm-Ho codoped fiber have been used as FSAs for passive Q-switching of Yb-doped and Er-doped fiber lasers [6]- [10].…”

A theoretical model concerning a double-cavity, pulsed, dual-wavelength Er-Tm fiber laser is built. In this laser system, saturation induced passive Q-switching of an Er-doped fiber laser and resonantly pumped gain-switching of a Tm-doped fiber laser are realized simultaneously. Related population transitions of the passive Q-switching and gain-switching processes in this laser system are described. Characteristics of the Er-Tm fiber laser are investigated and discussed with different pump powers and cavity reflectivities. Numerical results indicate that this double-cavity laser configuration shortens the lifetime and improves the maximum recovery ratio of the saturable absorber at high repetition rate.Index Terms-Fiber saturable absorber, Q-switch, gain-switch, Er-doped fiber laser.

“…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]. Its thin film is reported to have high chemical and thermal stability, making it efficient for pulsed laser generation due to its ability to withstand high power illumination from laser pumps [30].…”

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). The Sm2O3 thin film SA was fabricated in- The rapid developments in transition metal dichalcogenide materials as saturable absorbers (SAs) have been reported to be efficient materials for generating Q?switched fiber lasers. 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 order to achieve short laser pulses, Q-switching is performed by passive and active techniques. The passive Q-switching is based on the use of a saturable absorber such as fiber with graphene or carbon nanotube deposits [7][8][9][10][11] and un-pumped segments of active fiber [12,13]. In this case, the repetition rate of the generated pulses is determined by the pump power which limits the controlling of the laser pulses characteristics and the output power reached.…”

Actively Q-switched laser operation of a narrow linewidth compact fiber laser based on an Er-Yb double-clad fiber is presented. The laser linewidth as a function of the repetition rate and the Q-switched pulses characteristics for different pump powers are experimentally analyzed. Stable Q-switched laser operation with spectral laser linewidth of 73 pm in a repetition rate range from 90 to 270 kHz is obtained. The minimum pulse duration of 178 ns, maximum peak power of 30.5 W, and maximum pulse energy of 5.4 µJ are observed. The maximum average power reached is 1.1 W.
