    Step down circuit for laser control, help me to improve it.

    Hello there, I would really appreciate any advice, constructive idea or anything that could be improve on this circuit, it's design for a 4.5A laser diode. Thanks for your help.

    Nichia NUBM44-V2 laser diode datasheet, where I can find it?

    Got it! Going deeper on Nichia's page I found that they made 20W laser diodes based on arrays of 1W diodes, by your professional point of view, do you consider that it's better to implement an array of low power laser diodes, or go with high power laser diodes, thank's for the information...

    Nichia NUBM44-V2 laser diode datasheet, where I can find it?

    That's an excellent idea! I was able to find some good information about the reverse zener diode on Nichia's datasheets, but I'm not quite sure about the reverse diode at the output of the laser, 'cause it says that "it's used for electrostactic noise protection" insted reverse voltage...

    How can I identify this laser diode?

    Actually, yes, lol, well... I don't really remember where I found it, in fact I used it in an tracking with the Pi and it has an excelent resolution, there was an 62ohm SMD resistor in the input, could this be a clue?; separating the cells I found the Junctions, P-N, but also other caps, my...

    How can I identify this laser diode?

    Removing the glass, this package is totally unnkown for me... I'm able to identify the P-N junction, but there's no code, no number.

    Nichia NUBM44-V2 laser diode datasheet, where I can find it?

    Even using duckduckgo ain't able to find anything related to the datasheet, I already search in this forum but there's no new information about the datasheet. Thanks for the advice.

    Nichia NUBM44-V2 laser diode datasheet, where I can find it?

    Thanks for the information, I already contact with them, but there's no response.

    How can I identify this laser diode?

    How can I know about the laser power input and output, impedance, model, etc about this diode; I don't have a start point, books, articules, any information is useful. Thanks.

    Nichia NUBM44-V2 laser diode datasheet, where I can find it?

    Hello there, where I can find the Nichia NUBM44-V2 datasheet? I need especific values of the curves, ESR and all the things related to this element, I was able to find some information on Project 450, but it wasn't enough, can someone provide me the datasheet or any information related to this...

    Help - My First Build

    Hey men, the most basic drivers for laser diodes are based on LM317 if your diode consumes less than 1.5A (this is the best one to begin with, it's cheap), if you're laser diode consumes between 1.5A and 5A is better to use the LM338, using a simple resistor you can drive the diode (this...

    help: highest current to run NUBM44-V2 without heatsink

    https://www.ebay.es/itm/Housing-w-405nm-450nm-Blue-Glass-Lens-Fan-for-5-6mm-TO-18-Laser-Diode-Module/131992654651?hash=item1ebb60133b%3Ag%3A328AAOSwImRYG9dq I've made one on my own, but you can use this as a reference, it must be greater for a 12mm laser case. Actually, on DTR's lasher shop you...

    Mate, that's kind of tao bao, as gazer101 said "hit or miss", I don't have experience with them, but using ebay or amazon ensures your money, if you going to risk with this companies you should try lower amounts of money, if you're experience is good then buy expensive things.

    help: highest current to run NUBM44-V2 without heatsink

    Hey SomeLaserGuy, I'm already using that diode model, testing it in a power suppy I've discovered that at 1V to 3V3 (an average of 500mA) it's already burning, I had to used a FAN to keep it runing, but when pass like 45-60 seconds it will continue warming. By my own experencie, I reccomend you...
