“…But inserting an AOM inside a cavity and managing it externally, makes the system more complex and expensive. In the passive Q-switching method, researchers use different types of material having strong non-linear absorption properties [7,8] among which SESAMs [9,10], carbon nano-rods [11,12], graphene and graphene oxides [13][14][15], 2D transition metal di-chalcogenides [16,17], metal oxides [18,19], etc have provided excellent results. These material-based saturable absorbers (SAs), however, solve the problem of actively Q-switched laser i.e.…”

In this manuscript, the performance of a passively Q-switched fiber laser has been presented, where a segment of un-pumped erbium-doped fiber (EDF) is used as the saturable absorber (SA). We have taken an erbium and ytterbium (Er/Yb) co-doped double cladding fiber as the gain media for efficient pump absorption and checked the potential of the laser by changing the length of the in-house fabricated erbium-doped fiber saturable absorber (EFSA). For a fixed length of EFSA, variation of important system parameters such as output power, repetition rate, pulse width, etc, with the change of the pump power has also been reported. The laser has delivered pulses of a minimum duration of 1.35 µs with maximum energy of 2.8 µJ. The repetition rate varies in the range from 24.8 kHz to 47 kHz with alteration of the length of the SA. The central wavelength of the output spectra is 1566 nm.

“…Active Q-switching usually needs some electrically powered modulation equipment, such as electroor acousto-optic modulators [4][5][6]. In comparison with active ones, passive Q-switching has the advantage of simplicity and compactness, which can be obtained by applying saturable absorbers (SAs) in the system, included are semiconductor saturable absorber mirror (SESAM) [7,8], and some twodimensional (2D) materials, such as graphene [9,10], topological insulator (TI) [11,12], transition metal dichalcogenide (TMD) [13,14], and black phosphorus (BP) [15,16]. 2D materials have been intensively investigated in recent years owing to their outstanding mechanical [17], electrical [18] and thermal [19] properties.…”

We propose and demonstrate an in-band pumped all-fiberized passively Q-switched laser emitting at 1080 nm. A single mode 1030 nm fiber laser is used as the pump source, while a 2D material, CVD-grown monolayer graphene, is adopted as a saturable absorber inside the ring cavity. The repetition rate of the output pulses can be varied from 12.74 to 24.6 kHz with the pulse duration around 12 µs. The maximum average output power is 34.25 mW, with the pulse energy of 1.392 µJ. This work proves the practicability of achieving passively Q-switched operation via in-band pump.

“…Various SAs including the semiconductor saturable absorber mirrors (SESAMs) , carbon nanotubes (CNTs) , and graphene have been investigated and could play an important role in the characteristics of the Q‐switched lasers. While the fabrication of SESAMs is complex and costly, constructing CNTs and graphene‐based SA are relatively simple and cheap.…”

We report a room temperature all‐fiber dual‐wavelength Erbium Ytterbium codoped fiber laser (EYDFL) operating at 1543.3 and 1545.4 nm using a nonlinear polarization rotation (NPR) technique. An isolator is used in conjunction with a multilobed double‐clad Erbium Ytterbium codoped fiber to induce intensity‐dependent loss in a sufficiently high loss ring cavity to achieve dual‐wavelength and Q‐switching simultaneous operations. At the threshold pump power of 0.27 W, the EYDFL generates a sequence of pulses with repetition rate of 12.06 kHz and pulse width of 11.56 µs. When the multimode pump is increased to 0.60 W, the repetition rate can be tuned to 57.94 kHz. The lowest pulse width of 5.04 µs and the maximum pulse energy of 72.01 nJ are obtained at the pump power of 0.55 W. The simple and inexpensive dual‐wavelength Q‐switched NPR‐based laser has a big potential for applications in metrology, environmental sensing, and biomedical diagnostics. © 2015 Wiley Periodicals, Inc.
