Passively harmonic mode locking in ytterbium-doped fiber laser with graphene oxide saturable absorber

Abstract

Abstract. We have demonstrated the dissipative solitons generated in an ytterbium-doped fiber laser cavity using graphene oxide as the saturable absorber. The lasing light, centered at 1077.2 nm, has a 3 dB spectral bandwidth of ∼1.12 nm. Under different launched pump powers and appropriate polarization orientations, harmonic mode-locked of second-and third-order pulse trains have been achieved; the corresponding 3-dB bandwidth and pulse duration have been detected. © The Authors.

Graphene saturable absorbers applications in fiber lasers

“…PC, polarization controller; WDM, wavelength division multiplexer; YDF, Yb-doped fiber; ISO, isolator; GOSA, graphene oxide saturable absorber; SMF, single mode fiber. Taken from [133] MHz. In the experiment, a femtosecond laser was used as the light source for them, and the signal first passed through a variable optical attenuator (VOA), and then passed through a fiber coupler.…”

A Study of the generation of laser soliton from spontaneous emission by ring cavity with carbon nanotube

“…The power of the soliton grows exponentially once the power of pulse exceeds a threshold value, where at the power of soliton be at 0.007 W, and picosecond optical pulse is amplified in such EDFL, until gain saturates at with power 1.2 W. length at ,we see that the phase changing with time as cosine wave with rang 1 to -1as shown in Fig.8(a). The wave number in phase equation depends on the parameters , , c and width of soliton as shown in the following equation : (32) 32 let us consider the case in which the phase of soliton varies linearly along the fiber length as shown in Fig.8(b) at the phase of soliton , where and the phase of soliton reached maximum value at . It is clearthat the values of the phase will play an important role to building soliton from spontaneous emission in Er +3 fiber laser.…”

Passively Q-switched Nd:YAG laser with a MoS2solution saturable absorber

“…In the past decade some passively Q-switched lasers have been produced using GaAs crystal wafer saturable absorbers (SA) [2] and semiconductor saturable absorber mirrors (SESAMs) [3] as Q-switching elements. Recently, carbon nanotubes [4,5] and zero-gap material graphene [6,7] have been investigated for fabricating new types of SAs because of cheap cost, easy fabrication methods, and wavelength-independent saturable absorbing characteristics. Few-layer molybdenum disulfide (MoS 2 ) is emerging as a promising quasi-2D material for photonics and optoelectronics applications that further extend the collection of suitable layered nano-materials with exceptional optical properties in SAs that enable short-pulse generation in laser systems [8][9][10].…”
