Diode Laser Spectroscopy (Doppler-free Spectroscopy)
About the experiment
Laser is one of the most widely employed technologies in science and industry. In this experiment, you will be introduced to the concept of semiconductor diode laser, and its applications in spectroscopy and atomic physics. You will learn the basic technique of aligning a laser and observing phenomena, such as absorption and fluorescence. You will also learn about how to counter Doppler effect using saturated absorption to perform precision measurement in atomic physics. The basic technologies are relevant to the achieving of Bose Einstein Condensation using atomic gasses and the readout technique in the development of optical storage medium.
What you will learn
In this lab you will utilize a tunable diode laser to explore the absorption spectra of the Rubidium atom.
