Hello! I'm new here.
Three days ago i bought a 50mW Noname(tm) greenie.
Having searched the web for explanation of the SHG phenomenon i thought of a theoretical question:
If the IR LD emits 808nm which is transformed into 1064nm and then doubled by the KTP crystal to 532nm, what will happen if the first crystal is removed? What if LD shines a beam of 808nm through the KTP directly? My guess is that it'll double the frequency to 404nm - Hey! it's visible violet!
Of course, i don't wanna try modifying my laser in any way, but i'd like to hear if such a thing is possible.
(ow, i forgot- i live in Israel and it's quite hard to get a powerful laser here. i contacted some piratic sources, but i was lucky to find them.)
