Good build. +1 Beamshots pls

I don't know a lot about the properties of quartz; I would venture a guess the closer to UV you get, the more efficiency. If you can't afford a UV laser, I don't think a quartz lens would be an option either. They are near impossible to come by, and you might have to get one custom made. I don't...

A quote from wikipedia about fused quarts, *also note that there are many different types of quarts. "Fused quartz is manufactured by fusing (melting) naturally occurring quartz crystals of high purity at approximately 2000 °C, using either an electrically heated furnace (electrically fused) or...

If there's a box that is heated to 5000 degrees Fahrenheit, a 1400mw 445nm laser will literally do nothing. I can't think of any other reason to use 445nm laser besides burning at near room temperature; it has no niche, any niche it could fill, another wavelength would fill better. Also, as for...

Congrats Laik :D and shipping wont be bad either

Very generous Tonyt. :) +1 post #1

The little spring goes between the lens and heatsink for resistance. The big silver thing is where you would put your diode, i.e a module. I can't tell what the lenses are by this picture, can you post one showing the color that you see in each?

I'm not sure I understand the issue, are you unhappy about the wings on the dot? Or just that it's not a clean dot? You could try getting another lens, or even cleaning the diode window. I would rather just live with the laser as is, rather than risk damaging or worsening the diode windows's or...

@Bionic-Badger, great advice. But If having a degree is the important part, why is it ones ability to learn, not what one has learned? It seems that if anything in college measures ones ability and competence, it would be their grades, not the fact that they have a degree. Especially since many...

I did not tell him to look down the end to see green. I said if you looked at the crystal, i.e from above, like I said TOP VIEW, you could see green in there. If you looked down the aperture you could only see a future of blindness ;) I also did not say IR isn't very powerful. Please read...

@jcranmer I don't quite understand, why would the IR jump up in power once the green stopped lasing? It seems like the amount of IR should stay constant, or at least go down to me. The KTP is probably the thing that is out of place; It seems most of the light that should be going out of the...

Yep, everything has to stay somewhere in the system. :D If you were to look inside the laser, the top view of the crystals, you would see green light in there.

It would, except the green light is being reflected somewhere else, i.e inside the host. Again, I'm only half sure this is right :D

@LivinLoud, Actually it's probably safer than it was previously, because the IR was always there, only now you can see it. The laser could be more powerful than before, but only if the crystal were to be removed. The IR is still hitting the crystal, but at an angle that doesn't reflect well...
