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.
