Decoding Saturable Absorbers: Pivotal in Passively Q-switched Crystals
Introduction Photonics, a field centered around the creation, release, modulation, and detection of light, has seen immense improvements, particularly in the development of lasers. Q-switched lasers, capable of generating potent, fleeting light pulses, owe their operation to key components known as saturable absorbers. This article explores the role of saturable absorbers in passively Q-switched crystals and their contribution to laser performance. Understanding Saturable Absorbers Saturable absorbers are unique materials that lessen their absorption as the light intensity they’re exposed to rises. Initially, they absorb a considerable amount of light. However, as the light intensity escalates, the absorption process reaches a …
