Nd:Ce:YAG Laser Crystals
Water cooling systems add paralyzing weight and complexity to compact laser designs. ATR Crystal engineers Neodymium and Cerium co-doped YAG (Nd:Ce:YAG) to completely eliminate this burden. By radically suppressing thermal distortion while maximizing conversion efficiency, this advanced gain medium is the definitive core for miniature, air-cooled, and high-average-power laser architectures.Massive Output Surge: Delivers an exceptional 30% to 50% greater output energy compared to standard Nd:YAG under identical pumping conditions.
Air-Cooled Dominance: Exhibits remarkably low thermal distortion, making it the industry’s most reliable material for no-water cooling systems.
Versatile Operation: Flawlessly engineered to sustain severe peak powers across multiple dynamic modes, including pulsed, Q-switched, and mode-locked operations.
