OSA Student Chapter Meeting





MAIN TALK
SPEAKER: Zhenhuan Yi
TITLE:The Diffraction Grating and its application to External Cavity Diode Lasers
ABSTRACT:
"No single tool has contributed more to the progress of modern physics than the diffraction grating..."[1] We have seen this device contribute to every field of science. The physicist, the astronomer, the chemist, the biologist, all use it as a routine tool of unsurpassed accuracy and precision in a wide array of applications such as detecting atomic species, determining the characteristics of heavenly bodies and the presence of extraterrestrial atmospheres, studying the structures of molecules and atoms, and producing sophisticated laser sources... In this talk, we will go through some details of grating that may not be familiar by many people, and see how it works for the External Cavity Diode Laser(ECLD).

SPEAKER: Charles Ballman
TITLE: Quantum Measurement theory: A deeper look at Heisenberg's limit.
ABSTRACT:
The Heisenberg limit has been a proven relationship for uncertainties in quantum mechanics. However, these ideas were applied to the precision of a measurement and the disturbance that is created. It has been demonstrated that this limit is not the fundamental limit for measurement theory. The relation, which has broad implications for foundational quantum mechanics, will be briefly reviewed.
