    NUBM0G laser build

    Put a white phosp thing in the front so it doubles as a flashlight

    Pot mod green laser true?

    Want some fun take the module apart and try using a higher power pump diode. You’ll hit a thermal limit but that will do the trick. Alignment can be difficult. A lot of these use crystals with mirrors on the end of the crystal so they are aligned to start.

    Build & Review: 57X nm Module from TinkerTavern

    I have a little ocean optics box as well. Pm me if you are interested.

    Scientist Turn light into a " Supersolid " for the 1st time.

    Think about it if you could make a megawatt light solid that delivered its payload on contact…..photon torpedo!

    Build & Review: 57X nm Module from TinkerTavern

    If the camera is right tha looks about right with just a hint of green. Like a mostly ripe lemon. Mine came in at 573nm as advertised. This was on a Andor spec so I know it’s right.

    Allow TinkerTavern back? POLL

    I love the yellow I got from him.

    Chance to get a 300mW 607nm pointer module! Group Buy 607nm Orange pointer Modules!

    Message me the costs and maybe we can cost share and make it happen.

    Diode Window and Optics Cleaning

    I like first contact. Works no fuss no liquids.

    Continuum laser media

    I don’t have an opa but you’re right. What we are doing is looking for resonances in materials so we sweep a narrow wavelength tighter better until we find shg. Note it and move on. Then come back and narrow in as tight as we can to peak it. We expect uw of shg from this or nothing at all...

    Continuum laser media

    Yea I tried that. Works but not enough power. I think I’m stuck with the dye laser to get enough tunable power to do shg in the visible.

    Continuum laser media

    Anyone know a reasonable cost source for structured media for continuum? I need to pump it to make a continuum but I need enough power after the shift to shg to the UV. Right now I have a tisaph 980-800. So I can reach 490-400. But I’d like to get 600-400 but still have enough power for shg...

    How can I drive a laser diode at 1MHz for a speed of light experiment?

    But the edge is perfect no? See speed doesn’t matter for this experiment as your comparing the phase of two pulses. So slow is fine. Actually CW is fine in an interferometer. Fringes. Getting the path length right is most important. Thanks for the explaination. I never need a chopper for...

    How can I drive a laser diode at 1MHz for a speed of light experiment?

    More….why it blocks or it doesn’t. I have not used one for decades. I’d think it be instant on instant off. I however am assuming the speed remains constant.the blades are not bent, ect…. Now thinking of it you’d want to place it at the center of a set of lens too for the smallest spot size...

    How can I drive a laser diode at 1MHz for a speed of light experiment?

    What I’m saying is you don’t need to chop that fast. You just want a pulse train with shape edges.
