“…Up to now, enormous experimental data and simulation results show that optical fiber lasers can produce many categories of pluses, such as conventional solitons (CSs), dissipative solitons, stretched pulse, self-similar pulse (Peng et al, 2013; Li et al, 2016; Wang Y. et al, 2016; Chai et al, 2018; Zhang et al, 2018; Wang et al, 2019). At the state of multi-soliton, harmonic mode locking (HML) would be formed when the solitons repel each other in a long range and uniformly fill in the whole laser cavity (Yang et al, 2007; Wang Z. et al, 2015; Fu et al, 2019). In addition, another kinds of multiple pulse called bound solitons (BSs) or soliton molecules would be formed as well, when the solitons repel each other in a short range and attract each other in a long range then transmit simultaneously (Komarov et al, 2008; Wang Y. et al, 2015).…”

Gold nanorods (GNRs) has been investigated in the field of chemistry, optoelectronics, and medicine for their tenability, compatibility, electromagnetics, and excellent photonics properties. Especially, GNRs, used to generate ultrashort pulse, have been studied recently. However, multiple pulses evolution based on GNRs needs to be further explored. In this article, GNRs are synthesized by seed-mediated growth method, characterized systematically and been chosen as saturable absorber (SA) to apply in ultrafast photonics. The GNRs SA presents a saturable intensity of 266 MW/cm2, modulation depth of 0.6%, and non-saturable loss of 51%. Furthermore, a passively mode-locked erbium-doped fiber laser based on GNRs SA with femtosecond pulse is demonstrated. Thanks to the excellent properties of GNRs, by adjusting the cavity polarization direction with the proposed GNRs SA, soliton molecules operation with spectrum modulation period of 3.3 nm and pulse modulation interval of 2.238 ps is directly obtained. For the most important, 9th-order harmonic soliton molecules have been generated in the laser cavity for the first time. It is demonstrated that GNRs can be a novel type of non-linear optical (NLO) device and have potential applications in the field of ultrafast photonics.

“…[12][13][14][15][16][17][18] Harmonic mode DOI: 10.1002/andp.202200183 locking is a valid method to achieve high RPR ultrashort pulse without reducing the cavity length. [19][20][21] When the laser is mode-locked, the fundamental RPR of the output pulse is equal to the number of times light propagates in the cavity per second. However, in some specific polarization states, after nonlinear accumulation caused by high pump power, a pulse sequence is obtained with a shorter time interval compared to the fundamental mode locking.…”

As a new emerging semiconductor with interlayer bandgap, lead selenide (PbSe) have broad prospects in the fields of electrocatalysis, photocatalysis, infrared optoelectronic devices, optoelectronics, and ultrafast photonics. Among them, ultrafast photonics is receiving a lot of attention due to its ultrashort pulse, strong peak power, narrow bandwidth, and high repetition frequency. Herein, the properties are systematically studied of PbSe through various characterization methods. The modulation depth of PbSe is up to 30%, and its saturation light intensity is 7.86 MW cm −2 . Using the evanescent field effect, nonlinear fiber-based photonics devices has been successfully prepared based on the PbSe nanosheet solution, which can increase the bearable pump power. The 36th picosecond harmonic mode-locked soliton molecule is generated in the erbium-doped fiber laser, which corresponds to a maximum repetition frequency of 222 MHz. The results show that the signal-to-noise ratio can reach up to 49.1 dB which is higher than most previous works by now. The results revealed the potential of PbSe as an excellent photonics material in applications such as nonlinear optics, ultrafast photonics equipment, photoconductive detectors, and light modulators.

Mode-locked Yb-doped all-fiber laser based on in-fiber acoustooptic modulation

et al. 2011

Abstract:We show what we believe is the first demonstration of an ytterbium-doped strictly all-fiber active mode-locking laser. The active control of the laser is based on in-fiber amplitude modulation at 11 MHz, which is achieved by using an all-fiber acoustooptic superlattice modulator driven by standing acoustic waves. In our experiments, the laser was operated at 1091.3 nm and had two stable regimes producing either a train of mode-locked single pulses or a train of pulse pairs. Best results for the mode-locked train of single pulses were 740 ps of time width and 26 mW of average power, at a pump power of 480 mW.
