Synthetic Ruby Laser Rods (Cr:Al₂O₃) for Laser Equipment Length up to 200 mm
Product Overview:
Our synthetic ruby laser rods are grown using the Verneuil (Flame Fusion) method, a mature and widely adopted crystal growth process for laser-grade ruby. This method enables good crystal homogeneity, controlled chromium (Cr³⁺) dopant distribution, and reliable optical performance suitable for commercial and industrial laser applications.
Verneuil-grown ruby crystals exhibit high transparency, stable fluorescence behavior, and consistent laser output, making them a proven gain medium for pulsed ruby laser systems. Due to chromium doping and internal stress characteristics, the achievable crystal size is more limited than undoped sapphire; however, ruby rods with lengths up to 200 mm can be supplied depending on diameter and specification.
All ruby laser rods are fabricated with strict control of end-face flatness, parallelism, and perpendicularity to meet laser-grade optical requirements. Custom machining, polishing, and tolerances are available upon request.

Q1: What crystal growth method is used for these ruby rods?
A: The ruby rods are grown using the Verneuil (Flame Fusion) method, which is the most widely used and proven technique for laser-grade synthetic ruby.
Q2: What is the maximum available length?
A: Ruby rods with lengths up to 200 mm can be supplied, depending on diameter and application requirements.
Q3: Why is Verneuil-grown ruby commonly used for laser rods?
A: The Verneuil method offers stable optical performance, acceptable defect control, and cost efficiency, making it well suited for commercial and industrial ruby laser systems.
Q4: Can custom dimensions and tolerances be provided?
A: Yes. Custom diameter, length, polishing grade, orientation, and optical tolerances can be provided based on drawings or specifications.
Q5: How should ruby laser rods be stored and handled?
A: Store in a clean, dry, light-protected environment. Avoid fingerprints, mechanical shock, and rapid thermal cycling above 200 °C.
Store in clean, dry, light-protected packaging
Clean using methanol or other non-abrasive solvents
Avoid mechanical shock and excessive clamping force
