Webb13 apr. 2024 · The additive manufacturing (AM) industry has proliferated over the past few decades, from a modest beginning in the late 1980s with the advent of stereolithography (Wohlers & Gornet, 2014) to a global industry predicted to exceed US$34 billion by 2024 (Jayaram et al., 2024).In particular, metal AM has begun to infiltrate many high-value … WebbIn the case of Yb-doped lasers, the cryo-cooling provides further advantages. In cryogenic temperatures, the Yb-doped lasers become the four-level lasers, and consequently the laser threshold is greatly reduced. In addition, the emission cross section increases because of fluorescence line narrowing.

Webb30 apr. 1998 · Abstract: The average power capability of a solid-state laser is increased by cooling the lasing element to a cryogenic temperature. The laser pump chamber is configured to define a flow path for circulating cryogenic fluid. The cryogenic cooling is achieved for rod, slab, active-mirror or disc amplifier-type lasing elements.
