CO2-laser
Principle: Among molecular laser, the CO2-laser is of greatest practical importance. The high level of efficiency with which laser radiation can be generated in continuous wave (cw) and pulse operation is its most fascinating feature. The experimental equipment set is an open CO2-didactic laser system of max. 8 W power output. Since it is an "open" system, all components of the system can be handled individually and the influence of each procedure on the output power can be studied. One very primary and essential target in learning is the alignment of the CO2-laser by means of a He-Ne-laser.
Tasks:
1. Align the CO2-laser and optimize its power output.
2. Check the influence of the Brewster windows position on the power output.
3. Determine the power output as a function of the electric power input and gasflow.
4. Evaluate the efficiency as a function of the electric power input and gasflow.
5. If the gas-mixing unit is supplied the influence of the different components of the laser gas (CO2, He, N2) to the output efficiency of the CO2-laser are analyzed.
6. Measurement of temperatures differences for the laser gas (imput / output) for study of conversion efficiency.
