What is the difference between he-ne laser and ruby laser
Answers
Explanation:
Ruby laser requires a high power pumping source, whereas a Helium-neon laser requires a low power pumping source like electric discharge. The Efficiency of helium-neon laser is more than ruby laser. The defects due to crystalline imperfections are also present in the ruby laser.
Answer:
The difference between Helium-Neon Laser and Ruby laser are given below:Helium-Neon LaserRuby LaserThese are gaseous State laser.They are solid-state laser.It requires electrical pumping.It requires optical pumping.The laser output is continuous in it. It is in the form of pulse in the ruby laser.It has high efficiency.It has low efficiency.There are no any defects due to crystalline imperfections.The defects due to crystalline imperfections are present in it.
