chapter two
2.8i CO2 Laser System Configuration:
Three CO2 laser system configurations have been built in this project . The first configuration in our work (as shown in figure 2.6) consist from higher reflected electrode works as an anode terminal and output coupler electrode works as cathode terminal with one plasma discharge tube 0.75m long joining between them. The above system represented only one fold laser type.i
The second configuration consists from three blocks HR electrode and OC electrode both of them works as cathode terminal and the third block is the Bakelite electrode, which has two-anode pins terminal..i
There are two double jacket discharge tubes represent optical active medium joining between the two aluminum electrode with Bakelite terminal (see figure 2.7)..i
In both of the above system we have been used the same hemispherical resonator consist from plane, 60% ZnSe (OC)output coupler mirror and 10 m radius of curvature gold coated mirror as HR back mirror..i
The third and last configuration is the (v-configuration) which consists of two parallel folds, which consist from four electrodes. OC electrode and HR electrode both of them works as anode and joining the corner holder tubes electrode, which represent cathode by two discharge tubes..i
Then the corner holder tubes electrode connected with corner electrode by using Pyrex tube of 0.6m outer diameter and length of 0.8m(see figure 2.8).In this system we use the same hemispherical resonator with adding Gold coated plane mirror in the corner electrode use just as reflector..i
In the above three systems configuration we use the same CO2 gas mixture and cooled by the same chiller..i
HeNe laser has been used to perform the mirror alignment and we do the initial alignment once every thing for each part of the system and after evacuating the system..i
