505nm and 480nm diode RESULTS

I finished building my 502nm laser with the host I bought from Lifetime17. I was comparing it to other green lasers and even next to a 510nm diode it makes the 510nm look yellow. The 510nm looks blue compared to a 532nm, but the 502nm looks very blue compared to the 532nm. Still, by itself, it looks green. I found out that the 495nm diode I was waiting to measure fell through, so I won't have one of these to measure anytime soon. I really wanted to find a wavelength that on its own looks blue to me, but is still as close to 500nm as possible. I'm hoping to get another chance at getting a 495nm to measure.
 





Thanks. It turned out very well. I need to try to take photos that are representative of the color. :D
 
The problem with taking pictures of 505nm is that the color perception changes considerably depending on the environment. Mine looks bluer during the day and greener at night, and proximity to a 520nm makes it a lot bluer as well.
 
Exactly. My 502nm looks very blue next to a 510nm, and the 510nm looks yellow next to the 502nm. The trouble is a camera doesn't make these distinctions. It is something you have to experience in person to see the full effect.
 
Playing with the white balance on the camera gives a similar effect. It's how I was able to get the 485nm to look good.

Glad you finally found time to make a 502nm of your own Paul!
 
Thanks, Zach. I still have two or three <505nm diodes left, but they are case positive. I hate working with the Survival Lasers Blitz Linear driver, which is the only driver I'm aware of that can drive these diodes without isolating the diode from the host. Don't know if you have ever tried to use one, but they are a huge pain. I will play with my camera to try to get the best beam shots I can.

I have used two of the Blitz Linears on a pair of SB1573N91 and have found them a bit annoying, but not terribly so. The hardest part of using them is soldering to the pads (no through holes is a pain) or the tiny bridge to get into low current mode. They are alright. Given they are the only option I am not complaining about design.

Please, oh gods of the currents, steady our drivers to stay continuously-positive in your image. Bring forth examples of your purity by giving us more variety!

I have used them on three occasions and one was defective right out of the bag. The pot on them is tiny and cheap and I've found it to be the most difficult part of setting these drivers. BowtieGuy has had problems with two of them as well. I really wish there was an alternative driver.
 
Long time no see, Lighting Stalker. Are you just subbing, or do you want some information on these diodes?
 
Already ordered the laser diodes from DTR, looking forward to the 505nm Emerald green / Aqua green laser host soon, after I do the 450nm blue Osram diode laser (Beastly Blue). :D

*Off-topic: Apparently, the green Convoy S2+ LED flashlight host looks quite nice, especially the mint green anodizing coating, for the afrmentioned green laser diode I bought. Beastly Blue of course will be built into the same host, only with blue anodizing. I just like the styling.
(And yes, I admit, I have bought several Convoy LED flashlight hosts for my flashlights, including the DIY blacklight flashlight with Nichia NVSU233A-U365 LED.)

Stay tuned for some 495's and 488's coming out relatively soon. Within the next few months soon.

Nice to see a familiar username from a while back!

You will love the color. I don't know if Jordan got another batch of these as the first batch were closer to 510nm than 505nm. Either way it is very nice. I built a 502nm one recently and did a review of it and a 477nm build I did together. You should have a look if you are interested in what they will look like. :yh:
 
Not gonna complain, really. All I want to see is green within 500 - 510 nm ranges (Gallium Nitride laser diodes tend to be all over the place, it's the way they behave anyhow), and I am a happy camper. And I have seen the pictures of both 505nm LED and some 500 ~ 510nm lasers, I like the stopsign "Go" green color. I will look into your build.

I have the 520nm laser from DTR, and it's still nice. (Off topic, I wonder how I can clean the diode window - tried the Q-tip, it was no-go. I am not mad that I screwed up, as it wasn't powerful enough to char the crap on the window and it still lase just fine. I will have to be a "Careful Casper" on the 450nm diode as it can apparently destroy itself if it has a bit of dirt on the window, or worse, on the diode facet.)

EDITED: I took a look into your 502nm / 477nm build, they look quite nice, and color to match too.
