Endpumping

Endpumping is a term that can refer to several distinct concepts depending on the context, but it most commonly relates to techniques used in the field of lasers and optics. In the context of laser operation, endpumping describes a method of exciting the laser medium. This involves directing the pump light into one end of the laser cavity, often through a lens or mirror that allows both the pump beam and the laser beam to travel along the same axis. This contrasts with side-pumping, where the pump light is introduced from the sides of the laser medium. Endpumping can offer advantages in terms of efficiency and beam quality, particularly for certain types of lasers.

Another, less common, use of the term "endpumping" might appear in specialized engineering or manufacturing contexts, referring to a process of applying pressure or force to the end of an object, such as during metal forming or pipe joining. However, without further context, the optical and laser-related definition is the most prevalent. The precise mechanisms and advantages of endpumping in laser systems are detailed in laser physics literature and are crucial for understanding the design and performance of many modern laser devices.
