lifeline i do appreciate where you're coming from. what would you ask for a skyray? i don't think you see me. i'm pretty close to putting it into an altoid box (you might not get that one). i have a sink for the module.
hey jerry, i found a resistor that worked. dave told me this old tube needed one at both ends. i did have my polarity mixed tho. cathode got the 10k, i found a 75k for the anode.
it lases now. so i get to quit playing and get packing.
come on!! none of you oldtimers have like a sky ray or something? . one of those c-11 flashlights with heatsink or something like it. i have a kryton groove i'd offer, plus cash. i remember giving some pretty sweet deals in the past.
i'd like to drop in a 16x 405 diode/driver dtr...
as i'm moving i've been going thru stuff as usual. lit up an old red tube. beautiful!. i have a nice naked green tube i bought from dave a long time back. it needed a ballast resistor at both ends. the + one i have and it's 10k ohms.
the one for the - end i can't find. any idea what value i...
i've been away from lasers for a few years so i've lost touch with the people here. i'd like to buy an old used host i could drop a 12 mm module from dtr into. i'm going for a 405 16x diode run at ~500 mW used for short <60 sec runtimes so massive heat sink not needed. ideally i'd just want to...
techood sent me a replacement diode. this one is supposed to be the real thing. did anyone else contact them? they did seem eager to make things right and when i pop it into my groove i'll report back.
Just saw this on space daily. I wonder if they manipulate the wavelength using temperature or input current? maybe both? i never thought about using a diffraction grating for combining before, but I see now how it could work.
