What are the advantages of laser crystals?
High thermal conductivity
Laser crystals typically possess high thermal conductivity, enabling efficient heat dissipation during laser operation. This reduces heat accumulation, improving laser stability and lifespan.
Narrow absorption and emission bandwidths
The narrow absorption and emission bandwidths of laser crystals help reduce spectral broadening, improving laser beam quality and monochromaticity.
High transition cross-section
Activating ions in laser crystals usually have high transition cross-sections, meaning they efficiently absorb pump light and amplify laser signals, achieving higher gain.
Excellent optical properties
Laser crystals exhibit superior optical homogeneity and mechanical stability, resulting in highly directional, monochromatic, and coherent laser output.
Advantages of solid-state structure
As solid-state gain media, laser crystals offer better thermal and chemical stability compared to other media (like liquids or gases), along with higher mechanical strength and durability.
Birefringence
Some laser crystals exhibit birefringence, enabling complex optical effects in certain applications, such as generating polarized light or achieving optical parametric oscillation.
Suitable for high peak power and high repetition rate applications
Laser crystals are particularly suitable for solid-state lasers with high peak power, high pulse energy, and high repetition rates, making them crucial in industrial processing and medical surgery.
Diverse doping elements and shape designs
Laser crystals can be doped with various rare-earth ions (like Nd, Yb, Er, etc.) or transition metal ions (like Ti, Cr, etc.), and different geometries (like cylindrical, square columnar, etc.) can be used to meet diverse wavelength and application needs.
Long lifespan and high efficiency
Laser crystals typically have long fluorescence lifetimes and high quantum efficiency, maintaining efficient laser output over extended periods.
Wide range of applications
Due to their excellent performance, laser crystals are widely used in research, industry, medicine, military, and communication, including laser cutting, welding, medical surgery, lidar, and optical measurement.
