    NUBM44 6W+ 450nm Laser Diode

    Pman, Planters, and DTR, Thanks for the replies. Some other things came to mind today. 1) From start to finish (noticing the haze) was about 20 minutes. 2) I operated without the G2 lens for about 15 minutes. 3) The laser was operating less than 10 minutes total at various power levels...

    NUBM44 6W+ 450nm Laser Diode

    Regarding the distortion one person saw with the LD. I just experienced this with a 9mm NDB7875. I was working on different beam expanders and suddenly the beam got very “hazy”. I shined the raw beam (no optics) on the wall and the beam was very distorted and not uniformly bright. I tried...

    3.5W NDB7A75 445nm Laser Diode

    DTR, Awesome work - thanks for sharing. I'm trying to gage the power density between the NDB7A75 and the NDB7875. For example, if I focus both lasers at 20 feet which one produces the highest power density (watts/area) or do they both produce the same power density?

    Yobresal built 1.8W 445.. Burning Vid

    You need to work on your penmanship. Just kidding! Looks good. When I'm president, all preschoolers will learn to write with a laser.

    A message from our company

    You can see how Casio is sweating the laser safety issues by expending cost and manpower to develop methods to hinder laser diode removal. The need for product modifications most likely originated from their legal department trying to distance themselves from future liability by showing that...

    Ahh, nostalgia... How far we've come.

    Nostalgia? I worked with Toshiba providing independent testing of their TOLD series 670 nm laser diodes (gain and index guided) around about 1989. I used the tried and true LM317 as a current regulator with an initial separate current shunt to create a soft turn-on and soft turn-off to help...

    Iron Man Glove ^^

    By laser head, I meant the part that is in your palm.

    Iron Man Glove ^^

    I was interested in the head of your laser, and I was hoping for more detail than shown in the video. Like I posted before. Your design is pretty cool. I was thinking about making one, but not exactly like yours. My power supply is about the size of 2/3 of a 9 volt battery - this includes...

    Is there a chance you could please more detailed pictures?

    I can't stop watching the video - nice job! Do you have an estimate of the output power?

    8X Diode Murder fund

    Re: Lol ! I guess I'm missing something. But, if you would read through the thread, I was the person plotting the percent degradation versus operating minutes on a log-log plot after Igor posted updated data. The last update was when the diode was at 150 hours. It seemed that the updates...

    8X Diode Murder fund

    Re: Lol ! Wow, I wasn't trying to offend anyone or imply that Igor should dedicate 100% of his time toward this testing. I was just curious if the 1st 8X diode was still living.

    Any updates on the testing.
