That's very nice, and I do love Laserglow, but I was hoping for an option that isn't almost $100 after shipping...

I'm a physics undergrad currently working in an optics lab, and while I generally don't get to bring much of anything "home" (or even talk about what I do much) I've recently become more interested in lasers and purchased a couple. My brothers are both quite a bit older than I am and have...

A replacement part is already on its way to me. He has said I'll have to send in the part I currently have, which of course makes sense. They may want to take it apart to see what went wrong. Might help them prevent it happening in the future, which would only be good. Also the more time I spend...

Well if it was a simple fix there would be no reason to inconvenience JetLasers with an enormous shipping cost, so I wanted to be thorough. Simply demanding a replacement with no effort on my part seems a bit rude. I have already routinely been in contact with JetLasers and we have already...

The shape of the beam is very distorted now. Sort of a long rectangle, even where it was previously focused to a nice spot (~1in. from the aperture). Not sure what to make of this; perhaps something inside has completely fallen out of alignment, or the focusing lens is at some kind of angle...

So I've spent a few hours with it at my lab now. I tried pointing a heat gun at the mechanism for a while and turning it - no dice. I don't want to get too overzealous with it because these diodes can be rather sensitive to heat and while the case will provide some shielding, I'd rather err on...

I know which direction is the right one because of the location of the buttons and I spent a lot of time manipulating it yesterday while power testing it. I'll just have to try clamping it in the lab tomorrow and maybe using a heat gun on the focusing mechanism to see if it is epoxy or glue or...

He's been responding, he said to try heating it and to just try "more force". I've already used a wrench on it, and nothing should be holding it in place, so I'm hesitant to seriously brute-force it and completely torque the metal or break the internals. The thing is two days old.

A few weeks ago, after reading around to find a reasonably priced, trusted manufacturer, I purchased this 445nm 2000mW laser from JetLasers. It arrived yesterday. I did some testing at the lab I work in to check its power and get an idea of the heat it was producing to work out a duty cycle...
