    Mother of all red diodes

    Hi forum, I just finished mounting the mother of all red diodes. It is a custom-manufactured 635nm laser diode with an output power of perhaps 10 watts or more. Its lasing threshold is a whopping 4.5A, yet my power supply is only capable of 9. I'm sure it could handle at least 15. :-) Imgur...

    Thermal sensitivity of red diodes?

    Hi forum; I recently got my hands on quite a large red laser diode. I am not sure how powerful it is, /several watts at the very least/, but, the threshold current is 4.5A, and my power supply can only do 5 :-) >>Photo of diode<< Nonetheless, I have noticed a very strange characteristic with...

    Be safe.

    Scare story; do what you can to prevent my mistakes. It took 5 years' worth of laser experiments, but I finally managed to do myself in. Not with a 100W yag, or a 50W laserscope, but rather, with a divergent 445 diode. Here's what not to repeat: In one of our research labs' basements there is...

    Selling my Krypton

    Yes, a krypton, big fiasco blah blah. Here's a No Bullshit version of a krypton sale. Up for sale is my essentially brand new >750mW S3 Krypton laser. Overall she averages about that; 750mW. For lack of a better way to say it, it's essentially a handheld sunbeam. Provided the sun was green...

    FS: 1.45W lab laser - $750

    Well, I bought a very expensive ND:YAG deck which should give me 1000mJ pulses at 25Hz. This means about 8 watts of green if I align a few crystals correctly... This also means that I'm no longer going to need my 1.5W labby! 150 yard beamshot: Beam dot: TEM 11. Power Graph...

    FS: Tektronix Digital Storage Oscilloscope AND Signal Generator - $500 for both

    I've upgraded my scope; so unfortunately I must say goodbye to this fellow: It's a calibrated TEK TDS210 digital storage oscilloscope, and it works great. Has all the fun measurement and trigger features, plus what's down below: Bandwidth: 60 MHz Sample Rate: 1 GS/sec Record Length...

    Looking for a mirror galvanometer

    Hi LPF, I'm looking for a mirror galvanometer, one which would be suitable for directing a green beam to a new direction on every beat. Yeah I know, going to have to do a lot of EE for that but it's not THAT terrible. Willing to trade tritium lamps for one!
