Abstract

Stable picosecond dissipative soliton pulses were observed in an ytterbium-doped fiber laser employing a high-quality mixture of BP/SnSe₂-PVA saturable absorber (SA). The modulation depth, saturation intensity, and non-saturable loss of the mixture of BP/SnSe₂-PVA SA were measured with values of 5.98%, 18.37 MW/cm², and 33%, respectively. Within the pump power range of 150-270 mW, stable dissipative soliton pulses were obtained with an output power of 1.68-4 mW. When the minimum pulse duration is 1.28 ps, a repetition rate of 0.903 MHz, center wavelength of 1064.38 nm and 3 dB bandwidth of 2 nm were obtained. The maximum pulse energy of 4.43 nJ and the signal-to-noise ratio up to 72 dB were achieved at pump power of 270 mW. The results suggest that the BP/SnSe₂-PVA mixture SA has outstanding nonlinear saturable absorption characteristics and broad ultrafast laser applications.

基于 BP/SnSe2-PVA 混合可饱和吸收体的掺镱光纤激光器产生皮秒耗散孤子。

在采用高质量 BP/SnSe2-PVA 可饱和吸收体（SA）混合物的掺镱光纤激光器中观测到了稳定的皮秒耗散孤子脉冲。所测得的 BP/SnSe2-PVA SA 混合物的调制深度、饱和强度和非可饱和损耗值分别为 5.98%、18.37 MW/cm2 和 33%。在 150-270 mW 的泵功率范围内，可获得输出功率为 1.68-4 mW 的稳定耗散孤子脉冲。当最小脉冲持续时间为 1.28 ps 时，可获得 0.903 MHz 的重复率、1064.38 nm 的中心波长和 2 nm 的 3 dB 带宽。在泵浦功率为 270 mW 时，获得了 4.43 nJ 的最大脉冲能量和高达 72 dB 的信噪比。结果表明，BP/SnSe2-PVA 混合 SA 具有出色的非线性可饱和吸收特性，在超快激光器中具有广阔的应用前景。
