hello guys, i recently got an optlaser 568nm laser module, and while i was messing with the pots on the driver, the diode died, i decided to make a laser pointer with the small self doubling crystal i got from the 568nm laser, so i went to the store and bought a cheap 532nm laser pointer, i removed the 532nm mca and i added the 568nm crystal. (the 568nm crystal already had mirrored coatings on them) after around 30 min of aligning, i finally got yellow light! (568nm looks lemon yellow to me) i glued the crystal in place and i waited for it to set. when i came back, the glue had dried and the crystals were lasing, the output power was between 1-2mw and it was lasing at tem-01 but i got yellow light! and there was no mode hopping or anything. this process is incredibly inefficient (0.5%-0.8% efficient) as the pump diode was 350mw and i was getting 2 mw of yellow light output so i don't recommend you try this if you aren't that patient, aligning the 568nm crystals are much harder than the 532 ones and can take many minutes or hours to align . thanks for reading
