Answer 2

In Ruby laser, the atoms are excited by the flash tube.   (Option B)

• The flash tube serves as the energy or pumps source in a ruby laser. The laser medium receives energy from the flash tube (ruby).
• Lower energy state electrons in the laser medium obtain enough energy from the flash tube to leap to the higher energy state or excited state.
• The Ruby rod is put inside a xenon flash lamp to produce enough light to enable atoms to be excited. This type of pumping is known as optical pumping.
• As a result, in a ruby laser, atoms are stimulated by a flash tube. Option B is the right answer.
