Product Overview
The Alexandrite Laser Rod is an advanced laser gain material composed of chromium-doped beryllium aluminate, expertly produced using the Czochralski growth method. This rod excels in demanding applications like dermatology and Lidar systems, offering outstanding performance with its broad tunability and robust thermal properties.

Key Features:

  • Broad Wavelength Tunability:
    • Emission Wavelengths: Ranges from 710 nm to 800 nm, with a peak around 755 nm, allowing for versatile laser tuning.
  • Superior Thermal Shock Resistance:
    • Thermal Shock Resistance: Five times that of Nd, providing enhanced durability and reliability under extreme conditions.
  • Anisotropic Optical Properties:
    • Optical Characteristics: Absorption and gain are highly dependent on pump light polarization. The material’s strong birefringence enables efficient linearly polarized emission with low depolarization losses.
  • Material Specifications:
    • Formula: Cr3+:BeAl2O4
    • Crystal Structure: Orthorhombic
    • Unit Cell Dimensions (Å): 5.476(a) x 9.404(b) x 4.427(c)
    • Thermal Expansion (x 10?? K?¹): 5.9(a), 6.1(b), 6.7(c)
    • Index of Refraction (at 750 nm): 1.7367(a) x 1.7241(b) x 1.7346(c)
    • Melting Point: 1870°C
    • Mohs Hardness: 8.5
    • Density: 3.7 g/cm³
    • Thermal Conductivity: 0.23 W/cm·K
    • Young's Modulus: 469 GPa
    • Thermal Shock Resistance: 35 - 74 W/cm
    • dn/dT: 8 x 10?? K?¹

Applications:

  • Dermatology: Utilized in laser systems for skin treatments, where precise wavelength control and thermal management are essential.
  • Lidar Systems: Ideal for high-precision Lidar applications requiring broad wavelength tunability and high thermal shock resistance.

The Alexandrite laser rod is engineered to deliver precise, reliable performance across advanced dermatology and Lidar applications, providing both broad tunability and exceptional durability.
