Diode lasers for scientific research have a broad range of applications, such as pumping fiber lasers, solid-state lasers, or ultrafast lasers. They support advanced fields like nonlinear optics, quantum science, and laser fusion, contributing to the development and broader market application of laser technology.

Development of laser and its integration with relevant technologies have brought into being such inter-disciplines as laser manufacturing, communication, testing and medical treatment. This has provide a mass of new tools for cognition and transformation of the world by human beings.
