Visible light has an important and unique value in research and practical applications, because of its perceptible characteristics by the human eye. Directly pumped bulk visible pulsed lasers are booming in recent years stimulated by the advances of blue laser diodes. As critical components, novel and favorable saturable absorbers in view of distinct nonlinear saturable absorption properties are desired, which can promote the development of ultrafast photonics in the visible range. Over the years, low dimensional materials with the advantages of ultrafast carrier recovery rate and distinct nonlinear saturable absorption have originated a class of innovative applications in photonics and optoelectronics, especially as saturable absorbers in the pulsed lasers. Here, the low dimensional saturable absorbers in the visible range are reviewed, including the fabrication, linear and nonlinear optical response, and applications in the pulsed visible lasers of low dimensional semiconductors and noble metal nanoparticles. The design criteria of the low dimensional saturable absorbers for generating laser pluse by Q‐switching and mode‐locking are proposed and discussed. Finally, some possible development tendency and directions of saturable absorbers for the visible pulsed lasers are proposed in this review by focusing on some potential strengths.

可见光谱区域中的低维可饱和吸收体

可见光由于其人眼可感知的特性，在研究和实际应用中具有重要而独特的价值。近年来，由于蓝色激光二极管的发展，直接泵浦的可见光脉冲激光器蓬勃发展。作为关键组分，鉴于独特的非线性可饱和吸收特性，需要新颖且有利的可饱和吸收剂，其可促进可见光范围内超快光子学的发展。多年来，低尺寸材料具有超快的载流子恢复速率和独特的非线性饱和吸收特性，已在光子学和光电子学中引发了一类创新应用，尤其是作为脉冲激光器中的可饱和吸收体。在这里，我们回顾了可见范围内的低维可饱和吸收剂，包括制造，线性和非线性光学响应，以及在低维半导体和贵金属纳米粒子的脉冲可见光激光器中的应用。低维饱和吸收体产生激光脉冲的设计标准。提出并讨论了Q开关和锁模。最后，通过重点介绍一些潜在的强度，提出了可见光脉冲激光器的可饱和吸收体的一些可能的发展趋势和方向。
