The only one 40x40mm I found has 22mm diode mount.... could not find any with 20mm diode mount

By lab host you mean the little black modules with 30mm fan attached to it? Or something else? Can you provide some link to show what do you mean?

Okay so, I need two laser modules... 1. M140 2. Nubm44 I need both for cnc machines (m140 for engraver and nubm44 for cutter) Should I go for chinese laser modules with fan or should I purchase copper modules (35mm for nubm44 and 20mm for m140) from dtr with xyz holders? I need nonstop on...

Temperature is the thing Im thinking about... the mount is just some alu alloy and I need that for cnc cutter so the copper module would be better but I cant find any copper heatsinks with fan... just the cheap chinese or those from odicforce

Yes, thats what Im asking if I need to drill that hole or I can fit it there... thanks

Hi, its 18mm in diameter... im curious if I can fit diode’s pins into that tiny hole

Picture is now clickable so you can see the picture in original size

Hello, I would like to ask if anybody is using laser module from odicforce in combination with nubm44 diode. The diode holder seems to have hole for diode pins with too small diameter. Is it possible to use this module host with nubm44 host? Or do I need to drill that hole to make it wider?

thanks for your reply, are 26650s better than 18650? or just have more capacity? I prefer to use 18650s because I dont have any 26650s, but that wouldnt be problem to buy some. I saw some hosts from sinner that I really like, I think I will contact him as soon as I get the module. Id like to get...

Hello everybody, I'm planning to build nubm44 handheld laser. I found somewhere that it can output 7,9W @ 5.5amps but Im wondering what host should I use. Using survivallaser c6 or s4 host with so small heatsink would be very bad idea. Looking forward for your replies.

read pm :)

Duty cycle is about 1min on, this type of diode doesn't produce much heat. Im saving parts for another builds, don't want to have 5 same lasers :) Thanks :)

Hello, After making the guide of making cheap red laser build for about 33$ Ive decide to make another one, but much much cheaper. Part list: 10pcs Red Laser Diodes ML101U29-25 - 29.98$/10=2.998$ each 10pcs Laser modules 5.6mm with acrylic lens - 19.99$/10=1.99$ each 5pcs 9V battery clip -...

Nice laser, I did same laser as my first build but with blue ano heatsink and extended blue focusing ring :)

Yes, I hate making them too short too, but the final laser worths that :)

Ive found some other diodes with different power that have same specs as this one. Ive asked the seller for the info but he told me the same answer as the description.

Hello everybody, I need to know atleast model number, or max current it can eat. I don't believe the description on ebay. Ive found same description for more diodes. The datasheet would be good. High Burning Power 0 9 Watt 900mW 808nm Infrared to 5 9mm Laser Diode Gift | eBay

Thanks for the rep :) its impossible to fit it better because its too large, when I tried to screw it more I shorted the diode's pins.

Hello everybody, I used this schema to make drivers to run red diodes, but now I would like to make ddl driver to run IR diode, so I need about 2,2V @.5-1A, what changes should I do to this schema? I will use 3,7V 16340 battery. 3,7V - 1,5V(lm317) = 2,2V so voltage is good but the current...

no she isn't :/
