Today I graphed the first set of data taken with the optics set up.
- From a 90 degree polarization (vertical), I decreased the angle by 5 with the rotary polarizer and took the corresponding power measurement.
- At 0 degrees, naturally the measurement of power looked much like when the laser was turned off (11 nanoWatts).
- I used ND 2
- I will perform this experiment again on Monday with a more controlled and accurate measurement system.
- Afterwards, I plan to fit the data to show the relationship more clearly
- Random note..In later diagnostic designs, another power meter and laser splitter will be used in order to better understand the power of the laser.
Today I also found some useful information regarding our Iron Alloys
