    Undergrad Temperature increase by light absorption

    Hi, I have a question. If a crystal absorbs light and the absorption process leads to some excess energy being released as heat . Can one calculate the temperature rise or an experiment would most certainly need to be done? Apart from the heat capacity of the crystal before light absorption...

    Graduate How to Calculate Excited Molecules in O2 Gas Using Spectroscopy | Mark's Guide

    Hi All, Lets say I know the absorption cross-section of a gaseous species e.g. O2. I have a pulsed laser of a certain energy and of pulse duration, which will hopefully guide me with the number of photons and I focus that laser beam into a stream of O2 gas. Can I calculate the percentage of...

    Graduate Calculate % Excitation of Sample X w/ Laser Pulsed Source

    Hi Everyone, I am new to this forums. I am not sure where to post but general discussion is a good place. I am trying to figure out a problem: I have a sample X in gas phase. Say it has an absorption coefficient of 9.895e-18 cm2 molecule-1 @ 532nm. I have a laser pulsed source (say 50 Hz)...
