Study of biological photoreceptors by Ultrafast laser spectroscopy (CAT#: STEM-ST-0334-WXH)

Introduction

Photoreceptors are specialized neurons found in the retina that convert light into electrical signals that stimulate physiological processes. Signals from the photoreceptors are sent through the optic nerve to the brain for processing.




Principle

Ultrafast laser spectroscopy involves studying ultrafast events that take place in a medium using ultrashort pulses and delays for time resolution. It usually involves exciting the medium with one (or more) ultrashort laser pulse(s) and probing it a variable delay later with another.

Applications

study photoinduced dynamical processes in atoms, molecules, nanostructures, and solids
