Alright, so I figured I would write a quick list of the most common laser diodes that I have seen in builds recently. Obviously, the laser hobby has changed drastically over the last few years after these high powered multi-mode diodes were released. If you are an old-school laser hobbyist you may be shocked to know what kind of power you can expect from a semiconducting diode!
I have always been a fan of the blue (445nm-470nm) diodes but before the release of these high-power multi-modes I only really liked the 473nm DPSS (Diode Pumped Solid State) beam color. Those 473nm DPSS were fairly expensive a couple years back, and still aren’t cheap for your average Joe to go out and buy one; BUT now we have access to many awesome color blues like the 445nm-450nm M140 diodes capable of 2W output and at a fairly cheap price, or the beautiful “true blue” 465nm NUBM07E diode. I just figured I would let you know, I do have a ton of blue builds and actually favor them for the color and easily attainable power outputs.
Anyway, look below for the list of the diodes I feel are most common in the year 2016. I have read through a ton of build articles, and also purchase reviews from users buying pointers that have these same diodes as well; pretty much every well known laser company (JetLasers, Sanwu, DTR, TechHood) have these up for sale although the guys making complete pointers usually won’t advertise which diode unless you ask them directly. Sanwu is the difference there, as his pointers have details on the product pages of which diodes are used in that specific host. If you wish to get any more information like safe operating currents, or other information on these diodes it would be a good idea to visit DTR’s shop or the LaserPointerForums!
- BDR-209 – Maximum current of about 700mA with an output of 1 watt
- S06J – Max current of 450mA for 500-700mw output
- M-140 445nm 5.6mm A-Type Diode – Max current of 1.8A with an output around 1.8W
- M-140 445nm 5.6mm M-Type Diode – Max current of 1.8A with output ranging from 2W up to 2.4W
- PLTB450B 450nm Diode – Max current of 1.8A with output around 1.6W
- NDB7875 445nm 9mm Diode – Max current of 2.4A with output around 3W
- NUBM44 450nm 9mm Diode – Max current of 4.5A with output over 7W! WOW
- NUBM05 450nm 9mm Diode – Max current of 4.5A with outputs around 3.5W
- NUBM06 455nm 9mm Diode – Max current of 4.5A with outputs around 3.5W
- NUBM08 455nm 9mm Diode – Max current of 4.5A with outputs around 6W!
- NDG7675 465nm 9mm Diode – Max current of 2.2A with output around 1.4W
- M462 462nm 5.6mm Diode – Max current of 1.8A with output around 2W
- NUBM07E 465nm 9mm Diode – Max current of 4.5A with output around 5w!
- NDG4216 515nm 3.8mm Diode – Max current of 300ma with output around 100mw
- NDG700 520nm 9mm Diode – Max current of 1.8A with output around 700mw
- NDG7475 520nm 9mm Diode – Max current of 1.8A with output over 1W
- NUGM01T 520nm 9mm Diode – Max current of 2.2A with output over 1W
- Oclaro HL63193MG 638nm 5.6mm Diode – Max current of 1.2A with output around 700mw
- Mitsubishi ML501P73 638nm Open Can 5.6mm Diode – Max current of 1.2A with output over 1W
- Mitsubishi LPC-826, 836, 846 650nm 5.6mm Open CanDiode – Max currents range as well as outputs
These are just SOME of the common didoes I have seen in recent builds, there are many more out there. I think a good “starting out” hobbyist/DIY builder diode is the LPC-826 as you can get a pack of 10 for the price of 1 450nm M140 and they have fairly decent output at low currents. Hope you enjoyed, and if you have questions shoot me a message or visit DTR’s shop linked above.
