Excimer

Front 2

What is the difference between a CO2 pumping mechanism and the rest of the gas lasers?

Back 2

The only one that uses Radio Waves along with the typical electric discharge.

Front 3

What types of mediums are used in a CO2 laser?

Back 3

CO2, N & He

Front 4

What types of mediums are used in an excimer laser?

Back 4

Needs one from each of the 3 groups:
1) Ar*, Kr or Ne
2) F*, Cl, or Br (A halogen)
3) He

Front 5

What are the most common mediums used in excimer lasers?
