    565nm DPSS labby

    I tried looking for it through "565 nm laser" search query. but didn't find it. I'd like to buy a couple of them to have a volatile exchange fund, for converting them into gas lasers then:yh::yh:

    565nm DPSS labby

    Is there a chance that these lasers will appear on e-bay soon?

    Argon laser - Is this worth of buying?!?! Help

    I think that cooling it with a fan will not harm.

    Argon laser - Is this worth of buying?!?! Help

    This is normal for the MOT. All of them become very hot because the iron core works very near to the state of magnetic saturation. To reduce the heating it would be good to add a couple of tens of turns in the primary.

    Trying to build an insane 532 nm laser

    I think I will return to this project soon, as I've made the GOS1001 laser working. I've drawn a rough optical layout of the green laser. It will utilise 2 130W pumping chambers an a big lithium niobate crystal. Will this layout work? And where can I get a curved HR mirror for 45deg reflection?

    Household Deathstar

    Yes, it generates quite a lot of heat. Normal rate of fire is one shot in two to five minutes, depending on the pumping energy. So I adjusted the time of the caps to recharge to match this value. And 30 liters of water become warm after ten shots at 24 kJ. At this point output energy starts to...

    Some more holes in steel plates

    Household Deathstar

    Yesterday I managed to push 24 kJ of pumping energy. Estimated output is about 250-300J. Anyway, it cannot penetrate 3mm of steel from a single shot. The lens is with bigger focal lens and is not damaged now.

    Here I'm starting a thread about the most high-energy laser that had ever been manufactured commercially for general lab use. The GOS-1001 Nd:Glass laser, that is rated for 1000 J of output energy! And it is the true peak of my collection. A few days ago I managed to get first coherent photons...

    Rofin DPSS YAG metal cutting laser teardown

    It looks like that a HR from a pulsed laser should be fine for this. I've got a couple of them.
