“…The repetition rate of the Q-switched pulse increases with the increase of the pump power as reported in Ref. [69]. From Figure 6B, for a pump power of 630 mW, the average output power and pulse energy are 26 mW and 120 nJ, respectively.…”

Yttrium oxide (Y 2 O 3 ) has been widely used in metal-reinforced composites, microelectronics, waveguide lasers, and high-temperature protective coatings because of its good physical and photoelectric properties. However, few studies have been done on the nonlinear optical applications of Y 2 O 3 as saturable absorbers (SAs) in fiber lasers so far. Here, a passively Q-switched nearinfrared fiber laser using Y 2 O 3 as a Q-switching device is demonstrated. The optical nonlinear properties of the Y 2 O 3 SA prepared by the magnetron sputtering method were measured by the twin-detector measurement technique, and the modulation depth of the proposed Y 2 O 3 SA was found to be 46.43%. The achieved Q-switched laser delivers an average output power of 26 mW at 1530 nm with a pulse duration of 592.7 ns. To the best of our knowledge, this is the first report on the optical nonlinearity of Y 2 O 3 as a Q-switcher for the near-infrared fiber laser, which may deepen the understanding of the optical nonlinear properties of Y 2 O 3 and make inroads into the potential market of optical modulation and optoelectronic devices.

“…They had been investigated intensively using different kinds of saturable absorbers (SAs), such as SESAMs [1], carbon nanotube [2], and graphene [3]. However, due to some intrinsic drawbacks of those SAs, their applications were limited and researches had always looked forward to find new type SA with best performance.…”

“…Compared to active Q-switching, passive ones by means of saturable absorbers (SAs) have the advantages of compactness and simplicity design. Many kinds of SAs have been used to achieve passive Q-switching of the EYCFLs, such as Co 2+ :ZnS [3],Cr 2+ :ZnSe [4], and Co 2+ :MgAl 2 O 4 [4] crystals, semiconductor SAs [5,6] as well as fibrised liquefying gallium mirrors [7]. However, extra mirrors or lens have to be inserted into the laser cavity, which may increase the complexity and insertion loss of the configuration.…”

Compact passively Q-switched Er/Yb-codoped cladding pumped fiber laser

An all-fiber passively Q-switched erbium/ytterbium co-doped cladding pumped fiber laser is presented. A section of erbium/ytterbium co-doped fiber is used as both gain medium and saturable absorber, which makes the laser configuration simple and compact. By properly choosing the splitting ratio of the laser output coupler, stable Qswitching could be achieved. It has been found that the splitting ratio of the output coupler is very important for generating stable Q-switching pulses. The operation range of stable Q-switching is different for different lengths of the erbium/ytterbium co-doped fiber. Self-mode-locking effect is also observed accompanying with the Q-switched pulses. The characteristics of the laser output against the pump power and the splitting ratio of the output coupler are studied in detail.
