While working on my PhD degree at Purdue University, I have developed and built several optical instruments and modified many others to perform exotic experiments.
Shot-noise limited time-resolved circular dichroism pump-probe spectrometer
The work was published in Review of Scientific Instruments link
Modification of Ti:Sa oscillator to measure Circular Dichroism at Cryogenic Temperatures
The work was published as a part of Doctor of Philosophy Thesis at Purdue University see Chapter 5.2
