Re: 445nm Casio Laser Diode Compilation Thread It was from a XJ-A140, the power is output power in the emitted beam, without a lens. I will put some more videos on you tube soon, among others, probably one on how to fix the beam to make it a round dot. 0.707 is the RMS integrating number,it...

Finally pushed it to partial destruction! Finally damaged it ,drive current 2.3A and at 2.6W then it went to 1.8W and now operates at about 327mw at 650ma. Knowing this you take .707 x the power that injured/killed it and you have the absolute maximum safe drive power which is 1.84W. This...

The mode shifted to more of a uniform top-hat mode, I imagine this would make it a bit tricky to collimate at 2W- the now cold diode was tested when i returned home, still 528mw at 665ma so it is verified it didn't hurt it any. My guess is the XJ-A130 has 1W rated diodes, while the nicer ones...

Where did they get these diodes from, the Roswell alien crash? I got one up to 2.2W at 1.8A OMFG! Power measured without a lens, diode did not appear to be damaged from this brief 5 minute test. The calibration accuracy of my high range meter is 10% so it could be low of 1.88W to as high as...

This is a premiere product launch, from what i heard, they intentionally made them easy to extract the diodes. This was not for people building pointers, but for failure mode analysis and lower cost partial repairs or refurbishment of the laser module. The good news is they aren't going to...

A few thoughts: WL made these units and marketed them as weapons, they revealed the source of the diodes, and posted scary adds all over the net. Curious about revealing the source of the laser diodes... Why would they do this when they know a $700 projector has 24 of the diodes inside? My...

Re: Photos and Video of 445nm just posted a video in regards to one of these laser diodes testing various kinds of safety glasses, burning stuff, and yes lighting a candle. YouTube - HIGH POWER KILLER 1 WATT BLUE BEAM DIODE LASER LIGHTS CANDLE!

I made a portable with a cheap c-cell flashlight, and screwed the axiz module head into a disk of aluminum and then to the flashlight, it gets warm after running for a few minutes but not hot. The power is 600mw at the diode. The diodes need VERY substantial heat sinking if running at a full...

These are multmode, but not bad, you will need a cylinder lens or anamorphic prisms to round the beam. they work very nice for engraving stuff at slow speed, but cutting isn't going to happen realistically. It's actually very easy if you know what you are doing place the diode in the heatsink...

I think the MARKETING method is irresponsible, they are marketing them as a weapon, and dangerous device. This will attract the wrong type of people, just wait until one gets used as a robbery weapon or to intentionally blind a police officer. Then these and probably all laser pointers will be...

zap the anode end with the oudin, the big choke will take care of any danger to your PSU.

No but they can change their design a bit to discourage harvesting the lasers.

Re: 445nm Casio Laser Diode Compilation Thread My guinea pig diode was decanned when a speck of dust landed on the window and caused the diode to start melting it. After decanning the diode I tested went to 1150mw at 1.2A, and began mode shifting, but no sign of COD yet, i think there is not...

Re: 445nm Casio Laser Diode Compilation Thread I found that the optics inside can collimate all the diodes into a fat beam like a CVL. Pretty sick- 18W of average power output in an inch diameter blue beam. The two optics form a keplerian collimator- with a third correction optic you could use...

My though is, well.. all the work and money I spent fixing my 500mw melles griot blue dpss laser.. Now 1W of blue- sure a little bluer, and multimode, for only about $50.00 OMG- UFB! YOU HAVE GOT TO BE KIDDING ME, THIS IS A JOKE- RIGHT? Nichia was selling these at somewhere in the ballpark of...

This is amusing that the discussion on safety finally popped up with these class IV blue lasers, when the IR 1w + lasers have been out for years on the cheap. Hopefully this is the wake up call that we all need to give these devices the respect they deserve. The blue ones, especially at this...

Re: 445nm A130 Lens Comparisons! From the pics it looks like the stock lens inculded is spherical, this means they would not work good for most applications needing a collimated beam.

Your laser diode is a 30mw 780nm laser diode, the heatsink and mounting are very nice though, also keep that square lens before the polygon- you can use it to collimate multimode laser diodes :)

When soldering in a diode also make sure that you heat the part as minimally as possible. Some such as C-mounts and long OC reds will be destroyed with relatively little dwell time with the iron. The key to soldering these beasties in is HOT and FAST with a tinned part, and a CLEAN tip. I cannot...
