Laser Crystals

Laser crystals are solid-state optical gain media doped with rare-earth or transition-metal ions. When pumped by a light source—such as a laser diode, flashlamp, or another laser—these crystals amplify light through stimulated emission, enabling stable and efficient laser generation.

Laser crystals are valued for their high optical quality, excellent thermal stability, wide emission wavelengths, and compatibility with various pump sources. Different dopants (Nd³⁺, Er³⁺, Tm³⁺, Ho³⁺, Cr⁴⁺, Ti³⁺, etc.) produce distinct laser wavelengths, making them suitable for applications ranging from industrial machining to medical surgery, scientific research, and defense systems.

Common laser crystals include Nd:YAG, Nd:YVO₄, Ti:Sapphire, Er:YAG, Ho:YAG, Tm:YAG, and many others. Each crystal offers unique advantages such as high gain, broad tunability, ultrafast pulse capability, or strong mid-infrared performance.

Laser crystals are used in systems such as solid-state lasers, tunable lasers, ultrafast femtosecond lasers, Q-switched lasers, and high-power industrial lasers, covering emission wavelengths from the UV to the mid-infrared.
