It is always a bad idea to stare into the aperture of laser even if it appears unoperational.
Lasers are like guns: Good servants, BAD masters.
Do not play with those even with batteries/bullets taken out!

Anyhow, how is that alligning progress so far?

Default Re: [HELP] Repairing my 200mW Green Laser

Bad... It is very hard for me to stick the crystal back again, and put the diode back to the laser case and test it, if it is wrong, i have to take out everything again and alligne the crystal again

I have to keep repeating this process of taking the diode in and out again

Is there anyway that i can know whether i have alligne the crystal correctly?

If you can, try to keep the switch pressed with something, like a zip tie or something.
Then, if you have a battery holder , 2x AA or 2x AAA , connect the negative to the spring and positive to the brass case of the diode holder.

While doing so, try alligning the crystal that is partially glued, when you find a sweet spot, just jeave it there for the glue to dry out, but be careful, as H_Mike said, instant glue leaves nasty frost on every optics, so try to apply it on outside of the holders, if you can.

However, as much as I am a DIY person, I must say that it's too much of the trouble, and you will never get the previous power back.
It is all up to you, but I'd simply save for a decent laser from O-like or Rayfoss or similar.

if you have the laser up at eye level and put it in some clamps to hold it pointing straight up so that you can't see into it, you can then put the crystal bracket thing on top and rotate it until you see green on the ceiling then stick it. It's pretty much toast, but that's just another good reason to see if you can fix it or not.
