Laser Diode Endface Pumping
End pumping (also sometimes called longitudinal pumping) of lasers and optical amplifiers is a technique of optically pumping a laser gain medium, where the pump light is injected along the laser beam, rather than in a transverse direction (side pumping). Whether it is diodes for extremely high reliability applications such as LiDAR pumping or high-power pump modules for industrial and security applications, or customized laser diodes for scientific applications, TRUMPF Photonics is your OEM design and manufacturing partner of choice. We report on a new generation of high-power, highly efficient laser diode pump modules capable of delivering over 1. This development is fueled by enhancements in epitaxial design, chip design, and packaging technologies, which significantly enhance performance without. Fiber-laser manufacturers demand spatial beam profiles from a "cladding-free" 100-µm-core fiber-coupled module to avoid. The quasi-continuous 355nm laser is a quasi-continuous laser based on semiconductor laser diode (LD) end surface pumping.
