From what I have read, the frequency doubling mechanism is pretty intricate in these devices, and is based on a raman transition. Could someone explain the science behind these lasers?
At least one way to make 593.5 is from using a BiBO (BiB3O6) crystal to combine the 1064 and 1343nm output lines from a Nd:YVO4 crystal, which can pumped by an IR laser diode at something like 808nm.
At least one way to make 589 is from using a periodically-poled LiTaO3 to combine the 1064 and 1319nm output lines from a Nd:YAG crystal, which can also be pumped by an IR laser diode at something like 808nm.
It is the right thread, thank you for clarifying the situation somewhat. BTW, can you explain to me what is a raman transition? I am familliar with basic LASER science, but this part seems to have eluded me.
It's what happens when you add hard Raman noodles to boiling water they become soft.
