AHAHAH! I dont have any money right now! but thanks for the heads-up!
And Aryntha said he didnt know whats the math involved into doin the 561nm laser, and at first i thought it was an OPO like the yellow lasers and not frequency doubling, but actually its just a 532nm greenie, exactly like our other handhelds...
It uses the less efficient 1123nm line from Nd3+ and doubles it to 561.5nm.
So the coatings on the "mirrors" for the Nd laser are for that wavelength instead of the 1064nm line. The pump diode must be the same as one used, lets say to a 100mW+ greenie.
Just dont know if the doubling crystal is the same as the 532nm greenies.
All the coatings are for 561 and 1123 instead of 1064 and 532!
guess its easy, no? ^^
