Synthetic Ruby Laser Rods (Cr:Al₂O₃) – High-Quality Solid-State
Laser Rods 

Product Description

 


 
Synthetic ruby laser rods are precision-engineered cylindrical
crystals made from high-purity aluminum oxide (Al₂O₃) doped with
chromium ions (Cr³⁺). The chromium ions are responsible for laser
activity, producing intense, coherent red light at a wavelength of
694.3 nm. 


 
Manufactured using the Czochralski growth method, these ruby rods
offer excellent optical quality, uniform chromium distribution, and
minimal defects, ensuring consistent laser performance. With
superior mechanical hardness, chemical inertness, and thermal
conductivity, ruby rods are widely used in high-power Q-switched
lasers, scientific research, medical procedures, holography, and
educational demonstrations. 


 
Available in customizable diameters (2–20 mm) and lengths (10–200
mm), these rods are polished to laser-grade standards and can be
coated with AR or HR coatings for optimal performance in demanding
laser systems.

FAQ (Frequently Asked Questions)

 


 
Q1: What is a ruby laser rod?
A: A ruby laser rod is a cylindrical crystal made from synthetic
ruby (Al₂O₃ doped with Cr³⁺) used as a solid-state lasing medium to
produce coherent red laser light. 


 
Q2: How are ruby laser rods pumped?
A: They are optically pumped using high-intensity light sources
such as xenon or krypton flashlamps. The energy excites chromium
ions, which then emit coherent laser light. 


 
Q3: How should ruby laser rods be stored?
A: Store in a dry, dark environment as Cr³⁺ ions are
photosensitive. Avoid direct UV exposure and extreme temperature
fluctuations. 


 
Q4: How can I clean ruby rods?
A: Use methanol or other non-abrasive solvents. Avoid abrasive
cleaners that can damage the polished surfaces. 


 
Q5: Can ruby rods be customized?
A: Yes, diameters from 2–20 mm and lengths from 10–200 mm are
available. Surface polish and coatings (AR/HR) can also be
customized. 


 
Q6: What are the main applications of ruby laser rods?
A: Applications include high-power Q-switched lasers, holography,
medical procedures, material processing, scientific research, and
education. 


 

Storage & Handling Guidelines

• Environment: Keep in a dry, dark area to prevent photosensitivity damage.

• Cleaning: Use methanol; avoid abrasive materials.

• Mounting: Minimize mechanical stress; use soft indium foil for thermal contact.

• Avoid: UV exposure, fingerprints on polished faces, or thermal cycling above 200°C.
