Crystals

Optical Crystals are fundamental elements in laser and photonic systems, enabling light generation, frequency conversion, and modulation. Used extensively in defense, medical, and industrial applications, they play a key role in laser cavities, nonlinear processes, and passive Q-switching setups.​

We supply a broad range of laser, nonlinear, and passive Q-switch crystals, each manufactured from high-purity materials and precisely oriented for optimal optical performance. Our crystals feature high damage thresholds, excellent homogeneity, and superior thermal and mechanical stability, ensuring reliable operation even under high-power conditions.​

At Altechna, we support customers with performance measurements and technical expertise, including conversion efficiency and slope efficiency, near-field and far-field beam measurements, fluorescence lifetime measurements, and Findlay–Clay analysis for determining gain and internal losses.
