600mW 445nm 3x10440 build with gun barrel heatsink

I'm not an expert at this sort of thing. Constructive criticism is always welcome There are some things I would definitely do differently next time (list at end) but basically I am happy with it and want to share it!
Here is the stuff I used to build it. In the UK we have the lovely Maplin which I guess is like the USA's Radio Shack (do they still exist?) where you can buy really crappy "Rolson" 3xAAA LED torches "three for a fiver" kind of thing. The host betrays its poor quality by its clicky which is a bit coarse in operation. The housing is aluminium and quite thin and feels flimsy. Ah well. (Those wires on the driver, I took them off.)

Blue Laser Chat

It wasnt that long ago that it was said blue lasers were impossible to make then a japanese scientist discovered how to make blue laser light by accident, while trying to create blue LEDs. This was very exciting for the industry as the shorter wavelentgh was always going to be very useful for storage of bulk data on DVDs .... hence Blu Ray ! !

The first blue laser pointers to hit the market were 473nm , over £1000 and a truely stunning laser light to look at and these were only able to be manufactured as spare diodes became available from production of miltary storage storage products who were taking advantage of this shorter wavelentgh , however the military quickly moved onto even shorter wavelentghs so there no mass production of 473nm diodes , so prices of these in laser pointer or hand portable form are likely to remain high and on par with yellow lasers.

Then a bit of excitement , as mass market products such as DVD players / burners started being produced by the millions ( Blu Ray Products ) which meant loads of 405nm diodes available to be used in hand portable and laser pointers and laser pens , but in reality 405 is slightly fuzzy , slightly hazy and purple and not really that great or that useful so it has remained a hobbyist and specialist use laser

Now along has came 445nm Blue diodes ( 2010 ) being manufactured for use in display projectors such as casio XJA140 .... the incredibly exciting thing about these is the prices ! In early 2010 try and buy say 1000mW of 445nm and it would cost you £2500.... now people are paying £800 for a projector and literally ripping them a part as the unit contains 24 one watt ( 1000mW ) Blue 445nm lasers ... some hobbyist have built incredibly powerful 1000mW blue laser pointers and people who build laser projectors are jumping for joy as blue was always the most expensive part of their RGB setup , now its the cheapest and most powerful componant literally in the space of a few months.

We have seen them all and 473nm is a kind of light blue colour , 445nm is best described as royal blue and 405nm as purple , its not likely you will see a 445nm laser pointer or hand portable soon as at the moment the units are simply too powerful for handheld laser pointers ( 1 watt of laser anything is simply crazy power , and very very dangerous to eyes and skin )

445nm Blue Laser Burning STUFF 520mA

This is a video of my 445nm Blue Laser Burning some Matches, Electrical Tape,and a black CD case.It is set at 520ma dont know the mW but iam sure its around 500mW with the G1 lens.

I should be get my permanent host in early next week. :)

This is a high powered laser and burning stuff at this close range must wear the proper eye protection,even in none close ranges still need proper eye protection.Remember you only have 2 chance with your eyes do not risk it!!! Same goes if you decide to get the S3.

An lasers including The Spyder S3 arctic From Wicked Lasers are high power laser make sure to always use proper goggles and make sure they are the correct wavelength for you lasers.

Review of the Wicked Lasers S3 Spyder Arctic 445nm Blue Laser

The S3 Spyder Arctic G2 445nm directly-injected diode laser (hereinafter, probably just referred to as the "Arctic") is an extremely powerful self-contained, handheld laser.

It is rated to produce almost 1 watt of laser radiation at 445nm (spectrographically measured at 439.48nm {low} and 441.40nm {high}) in the royal blue part of the spectrum.

This is a CDRH Class IV laser device. Treat it with respect, and it'll treat you with respect.

This laser is water-resistant but not submersible, so please be careful around sinks, tubs, toilets, fishtanks, pet water bowls, or other places where water or water-like liquids might be found. However, you need not worry about using it outdoors when it's raining or snowing.

The case is made from 6061-T6 Aircraft-Grade Aluminum, and is treated with a black HA-III (hard anodized) finish.

1.5W 445nm Laser Burning Things

Here's the EXTENSIVE video. I performed 18 different "experiments" in it you could say I got a little carried away. The most impressive thing about this laser (at least to me) is how fast it pops balloons and lights matches!

Full ESD precautions were observed.

These diodes were harvested using NO HEAT.

Yours will be the first soldering iron these diodes have seen since they left the factory


For the diodes from an A140 unit:
$52 for the first diode, shipped in the US.
$47 each for any additional diodes in the same shipment


International add $2 for 1st class (no guarantee of delivery time frame), or add $10 for priority (6-10 days), or add $30 for Express mail (3-5 days)

Pressed into an AixiZ module add $5 each.
Pressed into a module with leads attached add $10 each.

Brand New 445nm 1W (1000mW) Blue Laser Diode in Aixiz Module

I am selling Brand New 445nm Blue Laser Diodes. It is a 445nm (blue) diode (fits a 12x30mm Laser Module case).

I recommend driving these at 500mA to get a high power at around 400-500mW, and have a stable long life. They have been driven up to 1000mA though to output 1W (1000mW). Heat sinking is strongly recommended as the diode does get hot from such high current, and using a short Duty Cycleis recommended as well. Also if powering this diode at 1A be sure to watch the wires from your battery source. This high of current draw can melt some skinny wires. Also I have read that using 18650 batteries is a good way to go as they can hold high amounts of mAh (battery power time).
