So, without the crystal only think I can do is change laser module? Or I can buy this crystal? Ps. I don't look in laser output, I watch using my phone.
Hello. I buy my first green laser (SDLaser 301) few days ago. Laser stop working after 5 seconds :/ I remove a upper part. I saw one small think, it wasn't hard to remove. I lost this. I remember, it have a lens on top, and something green, like a small crystal. I can fix it, or I must buy new...
