Describe about Helium-Neon Laser in short.
Helium-Neon Laser:
The first gas laser termed as Helium-Neon (He-Ne) laser (one of the illustrations for four level lasers) was constructed into 1961 year. The most general and inexpensive type of gas laser is generally constructed to operate into the red at 632.8 nm. Into this laser, the active medium is a mixture of He and Ne gas.
Can we take a negative test charge to find electric field?
VANDER WAALS BOND: A fourth type of bonding, which does not involve a transfer or sharing of electrons, is known as the Vander walls bond. It forms in atoms or molecules that b
What are the applications of laser transitions? Applications of laser transitions: a. High coherence of light is helpful for measuring length precisely by interferometry or
Q. In a galvanometer, increasing the current sensitivity does not necessarily increase voltage sensitivity. Explain An interesting point to note is that raising the current sen
