Abstract
The Ruby Rod is a cylindrical component crafted from synthetic
ruby (Cr:Al₂O₃), a chromium-doped aluminum oxide crystal. Renowned
for its exceptional hardness (Mohs scale 9), high melting point
(2050°C), and superior optical properties, it is widely utilized in
industrial, scientific, and medical fields. Synthetic ruby is
produced via methods like the Verneuil (flame fusion) or
Czochralski processes, ensuring controlled purity and uniformity
for specialized applications.
Historically, ruby rods gained prominence in 1960 as the core
medium for the first laser, and today, they remain critical in
precision engineering and advanced research.

Ruby Rod FAQ
Q: Why is chromium added to ruby rods?
A: Chromium ions (Cr³⁺) create a three-level energy system, enabling
laser emission at 694.3 nm and fluorescence-based pressure sensing
Q: How durable are ruby rods?
A: With high chemical stability, they last decades in industrial
settings, though prolonged exposure to >50°C may reduce
fluorescence efficiency.
Q: How does synthetic ruby differ from natural ruby?
A: Synthetic variants offer controlled purity and lower costs, while
natural rubies (e.g., Myanmar Mogok) are rare and prized for
collectible value.
