Saturable absorption - Wikipedia
Saturable absorption is a property of materials where the absorption of light decreases with increasing light intensity. Most materials show some saturable absorption, but often only at very high optical intensities (close to the optical damage).
Saturable Absorbers – passive mode locking, Q switching, lasers ...
A saturable absorber is an optical component with a certain absorption loss for light, which is reduced at high optical intensities. Such nonlinear absorption can occur, e.g., in a medium with absorbing dopant ions, when a strong optical intensity …
At the field maximum, either a bulk layer of a compound semiconductor or a single-or multiple Quantum Well (MQW) structure is embedded, which acts as a saturable absorber for the operating wavelength of the laser. The absorber mirror serves as one of the endmirrors in the laser (see Figure 8.3).

A saturable absorber is a simple and cheap substitute for an active modulator. Triggering of a pulse then occurs when the laser gain becomes so high that lasing begins despite the presence of the absorber.

饱和吸收体(saturable absorber)，是激光谐振腔内调Q技术中使用的一种开关晶体材料。 饱和吸收体对微光的吸收系数随入射光强增大而减小，当达到饱和值时对激光呈现透明，利用其这种饱和吸收特性对激光腔内的损耗(Q值) 进行调制，并发射脉冲，产生的脉冲宽度 ...
SA - Saturable Absorber - BATOP
Using a saturable absorber (SA), a self-starting, passively mode-locked laser with a very stable pulse repetition rate can be realized. SAs mainly for fiber laser mode-locking in a wide spectral region from 1030 nm up to 2800 nm wavelength are available.
In this work, we present a fully integrated CMOS-compatible artificial fast saturable absorber device using additive pulse mode-locking based on the Kerr nonlinearity[3]. We demonstrate saturable absorption behavior, with power-dependent device reflection, and a modulation depth of 4%. 2. Design and Fabrication.
