Applications
- He-Ne laser is mainly used in making holograms.
- In laser printing He-Ne laser is used as a source for writing on the photosensitive material.
- He-Ne lasers were used in reading the Bar Code which is imprinted on the product. They have been largely replaced by laser diodes.
- Nitrogen lasers and excimer laser are used in pulsed dye laser pumping.
- Ion lasers, mostly argon, are used in CW dye laser pumping.
