Instead of a typical “Advanced Laboratory”, our department instead offers an optics laboratory and a laser laboratory for our upper-division majors.
The first few labs are identical for
Then the students rotate through two sets of four labs.
Need 4 sets of everything in these labs. (Optical Tables, ND Filters, power meters, HeNe lasers, mirrors, hardware...)
Donated equipment includes CCD camera, optical tables, power supplies, HeNes, Optics, Hardware...
1st experiment: Use reference HeNe to align mirrors,
optimize power output, plot discharge current vs. power.
Increasing input power lowers gain (from ~15% to ~5%)
allowing estimation of saturation intensity for HeNe.
e.g. Gaussian Beam Lab, introduce M2≠1
