Hi everyone recently i was looking for laser crystals and since I am an autodidact i was confused by the terminology and units of the optics domain. And specialy by the absorption and emission spectrum sometimes the emission is expressed by (a.u) in tousnds and sometime from 0.0 to 1.0 i guess this is a percent am not sure. Second is the absorption wich use absorption coeficient $Cm^{-1}$!!

emission in tousnds

emission 0 to 1

absorption

So what is the difference between the two emissions unit?

How to read the absorpion unit? And is it better to have a high value or a low value for better absorption for the pumped incident?
(I am not a native so bear with me please thank you).

    $\begingroup$ Just as a side comment, a.u. means "arbitrary units", which doesn't have to be a percentage. It can be anything. $\endgroup$

  • $\begingroup$ @GabrielYbarraMarcaida "It can be anything" this doesnt look promising . $\endgroup$
