Have you seen that putty that turns purple when hit with a purple light? My kids got some for Christmas. I think the purple light is a 405 diode light but I am not sure. If you draw on the putty with it, the putty instantly turns purple there and fades away after some time. I didn't check it out in the dark or with a black light. It is pretty nifty, however it works.Quote:

The other recent oddballs (495nm, 505nm, and 473nm) appear to be singlemode . . and low power. All of this said, my wife tells me that my blue/green differentiation in the transition ranges is poor and likes to point out my occasional clothing mismatches.Quote:

No I haven't. I'll keep my eyes open for some as my daughter already likes drawing on the walls with a 405nm laser pointer (supervised as she is only five and the laser pointer is ~35mw). I wonder if your stuff is a zinc-sulfide or alkaline earth metal aluminate (apparently incorrectly referred to as strontium aluminate by me). I understand the AEMA purple and reds don't glow very long as compared with the greens and blues which can glow for 12-24+ hours when charged.Quote:

Thank you for posting, but didn't you promise something involving large numbers of photos in the past :rolleyes:
single mode I assume with beamspecs similar to other sm diodes ?
Will the availability be better than the last batch of cyanos ?
Hello,
I am a student at the City College of New York and am working on a project needing high powered lasers. Can the drivers that come with the laser be modulated? We are interested in analog modulation.
Also, do you have blue lasers at 465nm, 500-1000mW? The link on the website was not working. What are the costs of these?
Thank you!

Here is a link to the BBE driver that many people here on the forums have used with great success: https://www.ebay.com/itm/3A-analog-l...n/163377518563

DTR's website seems to be working fine for me.?.
Anyway, here is the direct link to the page with the M462 diodes: https://sites.google.com/site/dtrsla...nm-laser-diode They max out at around 2 watts.

Found a new longer focal length lens DTR-G-8 that is showing some pretty interesting results. Discussion thread on them over on the other site.
DTR-G-8
Most laser drivers I have on the site are simple compact drivers with either no modulation support or for the Super X-Drive it can support just TTL. However I do also have the Blackbuck 8M made by BBe as well which dose both analog and TTL. Also has other features not found on the smaller compact drivers I carry like the overheat protection which can connect to an external NTC sensor you would attach on the laser heatsinks to shut down the driver if exceeding 50C. All laser drivers I carry can be run continuously when properly sinked just like the BBe Linear that also needs to be sinked to run continuously. The BBe 3A Linear it is a great driver and I do plan on getting some here in the next batch he sends me due to requests for them.:beer:Quote:

No worries. You were helping the guy out. I did not even see the posts till I came to put a link for the new lens thread so I am glad that you did.:beer:Quote:
