Cr:YAG Laser Crystals
Active Q-switching adds unnecessary bulk, complexity, and cost to solid-state lasers. ATR Crystal engineers premium Chromium-doped YAG (Cr4+:YAG) to provide a highly efficient, passive alternative. Functioning as a robust saturable absorber, this crystal radically simplifies laser design, delivering high-peak-power pulses while strictly minimizing system footprint.Radical Miniaturization: Eliminates the need for high-voltage electro-optic drivers, drastically reducing overall system size, weight, and manufacturing cost.
Universal Compatibility: The definitive passive Q-switch for diode and lamp-pumped Nd:YAG, Nd:YLF, and Yb:YAG platforms.
Optimized Saturation: Precision-tuned for flawless absorption and intense pulsed outputs operating across the critical 1.0 to 1.2 µm wavelength range.
