Build for a green pointer?

[chaosfourever]

So can someone link how to build a green pointer using 808nm diode and a yag/ktp crystal? Be specific

a lot of people talk about doing it but i have never seen a finished diy green. aligning the crystals is just too hard from what i read. here is a link of the closest thing i have seen. http://laserpointerforums.com/laser_pointer_forums_3/forum/showthread.php?t=38684

p.s. i'm sorry if the link doesn't work, i am still getting used to the new set up.

I've built a few greenies with the bonded ktp/vanadate crystals, but that's super easy. Just stick it in front of a pump and you get green.

I've built one green with separate KTP and vanadate and output coupler, but I'm not quite finished with it

I'm working on my 473 with yag and LBO. I haven't gotten anything more than about 1mW yet. Still workin on it.

Ok so if I put my open can diode right next to a crystal that is both yag and KTP and attached to a heatsink then it will emit green correct?

anyone?

it's not that simple. but yes that is how. i'm not being a D but read the red and blu-ray posts. now compare those to the green posts. Do you notice a trend. Nobody is building greens. the consensus is that it is too hard. and special expensive equipment is need. That is the main obstacle.

I just bought a 3.5x3.5x6mm ktp. guess i gotta get the yvo4 and the rest of the supplies now.
