Blue laser under $300

mcreed87 · Sep 3, 2010

Hi all, I'm new here and new to building lasers. I have used them frequently in the past and taken a few apart but never built one. I do however have a degree in electrical engineering so I'm not afraid to try. My question is, and someone set me up with a list of all the parts I would need to build the most powerful blue laser I can for under $300. Or even recommend a kit. The reason I am asking is I had my arctic order cancelled and refunded out of the blue today and I'm done with WL. I also have no clue what parts work with what diode or lens.... Ect.... So I'm looking for a good parts list or a whole kit. Thanks in advance.

Welcome to LPF!!!

Look around and use the “Search” function, it is very helpful if you’re looking for some specific information. If you don’t find what you want the first time, try different “key words”.

A good place to start is here, the “Rules & Stickies” section, pay special attention to the “Stickies”: http://laserpointerforums.com/f36/

If you’re looking for information on how to build a laser check out the links in my sig.

Enjoy your stay!! You will find this a great community with lot of very knowledgeable, friendly, and helpful people. :beer:

You can find Jayrobs kits here. Stuff like hosts, heatsinks, lenses, and extras.
http://laserpointerforums.com/f39/jayrob-build-kits-lenses-other-stuff-listed-here-44227.html

You can buy a 445nm blue diode here capable of over 1 watt.

This is what you probably want to watch first:
YouTube - DIY: How To Build A 1W Burning Blue Laser Torch!

I just ordered this kit from LPF member "Jayrob":

$55 - Stainless Steel 18650 kit
$12 - Copper heatsink upgrade (for module)
$25 - Copper 1/2" module (for laser diode)
$48 - V5 FlexDrive 'Hot' option maxed at 1500mA
$15 - Driver heatsink installed
$24 - EzFocus FLUSH Adapter (threaded deep for AixiZ 445 lens)
$10 - AixiZ 445 glass lens (for pointing)
$45 - Optional 405-G-1 lens (for burning)
$12 - Shipping + PayPal fees

It was $201 minus the battery, laser diode and 405-G-1 lens. This will be a BEAST of laser almost exactly like this one:
http://laserpointerforums.com/f52/1...-custom-hot-option-heatsink-driver-54222.html

You can purchase the 445nm laser diodes (from a Casio XJ-A140) for $52 from LPF member "daguin". The best 18650 battery to use is this one: AW 18650 Protected 2600 mAh Rechargeable Lithium Battery

You can also do it the easy way and just order a non-focusable handheld from Dragon Lasers. I also have a Spartan 1.2 Watt 445nm blue laser on order (10-15 day wait before shipping) from here:
Spartan Series 1W Blue Handheld Laser, Rectangle Beam :: Blue Handheld Laser ----- 447nm Laser ----- Spartan Series Lasers :: Handheld Lasers :: Dragon Lasers

I have done quite A LOT of research into this recently and I have all of my notes. Please feel free to PM me!

Don't bother with modifying a flashlight host into a laser.

Contact Ehgemus for a custom aluminum host.
http://laserpointerforums.com/members/ehgemus/

Take a look at what he can do.
http://laserpointerforums.com/members/ehgemus/albums/custom-host/

He'll make you whatever you want and his expertise is second to none. Request a "direct press" diode host. That way you wont need an Aixiz module. Also if you're going to set the diode current >600mA then you'll want it to accept one 18650 battery. One CR123 cell won't yield a very long life if the current is too great.

He made this little host for me for like 45 bucks, so in the end you may save money. Plus he uses a high wattage switch and the threads are smooth as can be.

Trust me, don't bother with flashlight hosts and all those heatsinks, it's a pain. Get your host made for the part just as you want it.

Why not just buy a Spartan

Beautiful looking host!

How does all the wiring work inside that thing? Cause with most flashlight hosts, to connect a AixiZ module or even a flexdrive with a diode pressed in a module is about as easy as it gets. You basically just solder a few wires to the pre-made PCB board in the flashlight and you are done. Then simply screw it together.

From what I understand, the host you have there is more of a 'experienced' type of build. A direct press diode probably would be quite difficult for a beginner I imagine. At least with a AixiZ you can simple press the diode in with the back of the module. No special tools required (although you can use special tools to make it easier). And I am assuming with that host you need to solder a spring onto the back of the driver?

I think a flashlight host is about as easy and simple as it gets. Especially if you get a oversize one (much more room for wires and maneuvering stuff around). And they are very effective in heatsinking just as much as any other host (for the most part).

Although those Ehgemus hosts are simply amazing looking and top notch quality from what I hear.

Its more fun to build your own.

Also you know what's inside .. and you can replace easily any parts.

With respect, the 1W laser torch video is not a complete tutorial and there are some things missed out. Although it was made by a member here it does not cover everything needed to safely build one. I hope you did order a glass lens from somewhere? You'll need one.

I don't happen to think a 1W blue laser is the best for a, "First Build". The power is obviously very high plus you will have missed all the fun of working up to a 1,000mW! There's plenty of satisfaction and knowledge to be had at the lower end first. Learn some skill and kill some $10 diodes, (or even free ones from inside DVD burners), first. You're also not going to be working with something that's a fire hazard when you really don't know how to handle them yet. You can add some cash to the figure quoted above for a Jayrob kit because you need goggles too.

Your choice but you're missing out in my opinion and trying to take a short cut.

My bad, I already own a pair of OD 4 laser safety glasses and I forgot to add it to my list...

SAFETY GLASSES ARE AN ABSOLUTE NECESSITY WHEN WORKING WITH HIGH POWERED LASERS!

He asked about building high powered blue laser for under $300 so I was just trying to help. Mind you, the laser I have on order is not my first build. I have several custom 532nm greens, 650nm reds and 405nm violets I have worked my way up from.

Point well taken Morgan

The diode gets pressed directly into the aluminum heatsink which screws into the body of host. IMO is is not anymore difficult to build. In many ways it's easier because like I said it's all one solid piece. You don't have to fuss with heatsinks and setscrews and what not. Everything lines up perfectly the first time. The lens screws into the focusing ring and also into the front body of the host. Yes it's true you'll have to make a diode press, if you don't have the back to an Aixiz module (but even the back of the module is not recommended). I got a 1/4in aluminum rod and drilled a 3/16in hole in one end of it. That allows the leads to enter so the press does not stress them. You'll need either a vice or a press of some kind to get the job done.

For any "first timer" the expense will always be a little greater because you'll need to buy any tools or supplies that are needed. But seeing as mcreed is an electrical engineer I'm sure he has a soldering iron on hand.

I wouldnt bother with the expensive G1 lens. If you want every ounce of power its great, If you don't own a laser power meter though, in practical usage the $10 Aixis beam will give a better dot / beam at the cost of a little power.

I agree with this too. Hell even my 6x build has an acrylic lens. I'm a wavelength guy. I don't really care if my lasers aren't too powerful, and buring stuff gets old real fast. IMO if you're buying a laser just because you want to "burn" stuff, that's pretty childish. Just my opinion of it...

I understand you were trying to help, and you did. It's easy to overlook what's obvious to ourselves.

As they say, "The devil is in the details"!
