We tried to see some absorption yesterday. We saw florescencefluorescence at the wavelengths we expected to, but the numbers from the photodiodes aren't too convincing. Our setup is shown to the right. For each wavelength of light we took the ratio of the photodiode signals. Scanning over the wavelength was not done too systematically. We tried to get as many wavelengths as we could close to where the peaks should have been. We adjusted the wavelength by adjusting the grating angle, current, temperature, and piezo. We saw fluorescence at wavelengths near the peak, but the quantitative data does not look as good. Our results are shown [https://wiki.physics.wisc.edu/yavuz/images/4/42/Absorption_Data.pdf here].
