Pretty sure the G7 had an even longer focal length than the G8, so focal length is probably out of the question. I am not aware of any significance the G-number has aside of it being a name. If you're looking to focus farther away, beam expanders are probably what you want to start with. If...

Yup, they would behave similarly to pixels in the additive sense. Mixing is best if they overlap, be it by polarization or by allowing one range of wavelengths to pass and another to reflect. Not sure what your R&D budget is, but there are kits and guides for making your own RGB lasers, as well...

Nothing that is easy to find at the moment. Your best bet is GH0393AA2G from Sharp, though it's rated for 300mW. You can probably drive it pretty low. Group buy may or may not happen here https://laserpointerforums.com/threads/sharp-395nm-300mw-diode-gh0393aa2g.108325/ Can I ask why? I own one...

Absolutely true, but I argue it also goes down to use cases. Is the lifetime a problem for the OP? If its just a pointer project, $20 to replace a blown overdriven diode isn't too bad considering the cost of something actually specced there or higher. If it's for something scientific or being...

See PLT5 450B for ~300mW I don't think anybody here posted testing results on Sharp's GH04580A2G, being nobody has I'd err on the side of the osram diode being superior. Any particular reason you need single mode over multimode?

Yeah I'm all over that M462 lol. @farbe2 - This osram diode does not have the square box reflection, one of their selling points that they actually advertise though of course I'm struggling to find it now. Similar to what you've done here, they darken the die and substrate and I believe also...

I only really added fog to make the beams more visible. However, it is also true that the 505nm is maybe 30mW and the 405 and 650 are closer to 300mW. I excluded my 1.5W 532nm to avoid washing out the picture, and avoided 355nm because that is totally invisible to my camera

Wall plug lasers I own, minus 532 and 355. 405/450/473/488/505/561/575/589/607/635/650 I want to get a pic of my entire sig, but I have to get a camera that can handle the green-yellow range, and a few more odd diodes to fill in the remaining gaps.

If these end up cheap I'll be sure to make some noise about it. Unfortunately unless your budget is 5 figures that won't happen anytime soon hak

Yes you'll want some additional metal in there. Risky in my opinion to try stretching out the spring, but it's most likely the spring getting deformed over time in there. It happens. Less likely but possible the entire module shifted forward, you'd notice the button not pressing correctly as...

Yep diode is rated for 2W. Keep me in the loop, I'm interested as long as the size is manageable for something portable.

Wouldn't have posted if I wasn't ;) I paid 320 on the assumption I would fix it, since that that wavelength is no longer offered. What's your take on its worth?

If you're interested in projects, I have a 593.5 that only occasionally lases that wavelength, when it wants to. Its just the module in a custom host, not the original from cni. Bought it sort of as a project, but never had the time or motivation to do much with it. I suspect most of the...

Hey everybody, I got something crazy again. After over 10 years in the hobby I finally managed to get my hands on my dream laser. I spent some time talking with @Phillip here about some odd laser diodes he can get his hands on, and our discussion drifted in the direction that I already have a...

Likely not going to see much difference between the two considering how we can already push the 4W10 ones well past 1.5W. See here to compare specs: http://global.sharp/products/device/lineup/selection/led_laser/laser/index3.html

Those 375s were Ushio, not nichia. Otherwise agree, phillip is the way to go right now for one. Though a word of warning, those diodes are very sensitive to heat and have an operating range of 20-30C. I'd hate like heck to see one die from what usually gets considered normal use. Sharp is...

Pretty sure Thorlabs themselves manufacture it.

FYI - You're looking at a ~$4,200 price tag for any 480-495nm diode at any power higher than the sharp GH04850B2G can offer. You may be able to get around it just a little by combining two diodes with a PBS, but any more is really not that feasible in a handheld... and it won't make it to the...

Yeah the 47xnm diodes came and went fast. Someone has some nichia diodes for sale in that range right now though on the forum. 488s will probably be around for a while, sharp pumped out tons of them. Pretty sure jayrob checks in every now and again but isn't all that active anymore. Rich...

Giving you a bump - Will be grabbing one of the low wavelength diodes since I have a few already between 473 and 480nm. These are probably too expensive for most, but if anyone is on the fence I highly recommend a high wl diode, that electric blue color is awesome.
