small sun malfunction

i baught a zy-850 green laser a couple weeks ago and a day ago the laser would go off repeatedly. if i shook it a bit it would stay on . today it turned on for a second and then went off and wont turn on any more. do these "symptoms" sound familiar. ive seen this behavior with my led flashlights. can i fix this?

Hm, randomly going off and shaking it helps, you say? This is very weird.

I have not seen such sympthoms so far. I can think of uhh... maybe the crystals getting loose. It would explain it.

Grab a cellphone or a webcam. Point the laser at the white paper. Even if there is no green dot, if my theory is true, you should be able to see pink/white dot through you webcam. That's Infrared radiation emitting from the pump diode, not being turned into green since crystals got loose.

Post results, we'll work from there.
