What does PIPS stand for in the context of laser technology?

In the context of laser technology, PIPS stands for Photon Induced Photoacoustic Streaming. This concept relates to how laser energy can be utilized to generate acoustic waves through interactions with materials. When photons from a laser are absorbed by a medium, the energy can lead to rapid thermal expansion, which in turn creates pressure waves or acoustic signals. This phenomenon is particularly significant in fields like medical imaging and therapeutic applications, where photoacoustic imaging provides detailed information about tissue composition and structure.

The definition encapsulates the principle that underlies a variety of laser applications, distinguishing the accurate interpretation of PIPS in contrast to other similar terms related to photonics which do not convey the specific mechanism involving acoustic wave generation linked to photon absorption.
