“…Figure 3A presents the output wavelength centered at 1089 nm. The trace given in the figure is similar to other reports that addressed similar setups 8,9 . Further research is required to develop a mode‐locked laser based on SnO 2 as SA in the NDFL cavity with vector soliton or dissipative soliton.…”

“…In comparison with the above‐mentioned gain media, PQFL based on neodymium‐doped fiber (NDF) as a gain medium has relatively attracted little attention due to the immature manufacturing technology. Only a few reports have addressed Nd as a gain medium for PQFL application 8,9 . Both NDF lasers (NDFL) and Yb‐doped fiber lasers can generate lasing at 1089 nm.…”

A 1089 nm Q‐switched laser has been successfully developed by using a neodymium‐doped fiber (NDF) as a gain medium and tin oxide (SnO2) material as a saturable absorber (SA). The SnO2 SA was obtained by embedding the compound into a polyvinyl alcohol (PVA) host polymer so that it can be easily integrated into an NDF laser (NDFL) configuration to modulate the cavity loss for pulsing operation. The laser output pulse duration and repetition rate changed from 6.7 to 4.2 µs and from 55.8 to 72.5 kHz, respectively, when the 808 nm pumping power increased from 160.0 to 252.7 mW. The laser exhibited a stable output since we recorded a signal‐to‐background noise ratio of 46.4 dB. We believe that this work is the first to address SnO2 as SA in an NDFL cavity.

“…This is because the length of the waveguide causes changes in the pump power and signal power in the laser. When the pump light is continuously absorbed, the power of the pump light is getting smaller and smaller, which will cause the number of reversed particles to increase, and thus the intensity of the signal light will increase [11].…”

Erbium ions (Er3+) exhibit good characteristics of fiber lasers in the 1500-1550 nm band, including three-level systems, high tilt efficiency, and large emission cross sections. This article focuses on studying the spectral characteristics of erbium ions, simulating the power propagation equation of erbium-doped ion fiber lasers, and calculating the pump power threshold and output power. The findings of the simulation indicate that the laser begins to produce 10 W of pump optical power. The laser power hits 34.38 W and the oblique power is determined to be 38.20% as soon as the pump power exceeds 100 W. Experimental results show that when pump light propagates forward, the forward propagation power of the pump light will weaken, the forward propagation power of the signal light will increase, the reverse propagation of the signal light will weaken and the reverse propagation of the pump light will Transmission will also weaken, with directional transmission remaining largely unchanged. This study carried out numerical simulations on the experimental parameters of the fiber laser doped with Er3+and finally obtained the output power of pump light and signal light under these conditions, providing better data support for the preparation of 1500-1550 nm fiber laser doped with erbium ion.
