Cr3+doped/(Cr: Al2O3) sapphire crystal block Highly frequency Ti+ doped (Titanium doped)/ Cr+ doped sapphire single crystal used in laser / optical / sapphire laser crystals, ruby sapphire lens Ruby rod for laser What is Ruby Laser? What is the Principle of Ruby Laser? Spiking in Ruby Laser? What are the uses of Ruby Laser? Explained
Ruby is a three-level laser material. It is generally made of a
high-performance aluminum oxide crystal with 0.03 - 0.4% Cr3+,
which is made into artificial ruby, which is much better than
ordinary natural ruby. performance. Common ruby rods range in size
from 0.5 cm to 2 cm in diameter and 4 cm to 16 cm in length. It may
look like a very light pink glass rod or a very deep reddish brown,
depending on the concentration of Cr in the stick. It will be very
special to get in with a green laser pointer.

Ruby is one of the hardest known materials with the consistent quality
available on a commercially economical scale.
With a hardness of 2300 HV, it is much harder than most of the
known hard materials like ceramics, etc.
Ruby raw material is grown in a factory by Melting ultra-pure Al2O3
at a temperature higher than 2000 deg. Celcius creates a single
crystal.
This hard material has the ability to be polished to a very good
surface finish.
Sapphire and Ruby Ball Lenses. Sapphire and Ruby ball lenses are
both made from Al 2 0 3. Ruby or Ruby-Doped sapphire owes its red
color to traces of chromium oxide (chromium content for ruby balls
is typically>0.5%). While their physical and chemical properties
are basically the same, their optical properties are somewhat
different.
