Here is my new BluRay build. The box is made from aluminimum and acts as a heatink in itself. The aixiz module has a heatsink made from washers that have heat transfer grease in between them. These washers were then squeezed together before being glued to the aixiz. There is also a washer glued...

I have a BR laser. The diode is a PHR-803t. I have done some reading on here and found that the ideal current is between 120-130mA. My diode is currently running from a 9v battery, although it is an old battery now and is pushing out 7.7v. Using a test load I have seen that the diode is...

Hi all. I am about to buy and build a BR and Red lasers. The BR will give out about 100mW and the Red about 250mW. At these powers, especially the Red, there will be a lot of heat generated. The lasers are going to be in aixiz modules and then fitted into these boxes. I would like to have a...

Sorry if this has been asked like a million times before but I have heard of this on various topics but havn't found a topic that explains it. What exactly is an open can diode and what, if any, are the benefits compared to an ordinary diode? Can ordinary diodes be turned into open cans? Thanks.

Just a quick pic to show my BluRay that arrived today (thanks BluRay). Pic also shows one of my reds and greens too. The BR is cool. 125mw so it can burn a few things. I also popped a balloon filled with water from about 10 feet away lol. The beam had to be focused to a pin point, which was...

It's Farnell. Laser diodes here: http://uk.farnell.com/jsp/search/browse.jsp?N=500006+1002430&Ntk=gensearch_001&Ntt=laser&Ntx= They are low powered. Highest is 55mW (unless you want a 200mW IR diode). Any good?

Could someone do me (and other UK residents that want to build a laser) a favour. I have seen on this site that there are two main laser drivers. Both have been made in the USA and seem to work using batteries available there. However here in the UK we mainly use AA or AAA batteries that are...

Here is a simple spirograph I made. The kids love it lol. I know spirograph's are 'old news' but I thought I'd show it off. The insides are simple, just the two motors and battery pack.

I have a question about this laser driver: http://www.laserpointerforums.com/forums/YaBB.pl?num=1185701612 I am going to build this driver so that I can make my own burner laser into a torch host that I have. I have read somewhere that you really need to connect a dummy load to this driver in...

Does anyone know of any UK companies that sell AixiZ modules and laser diodes on thier own? I'd like to have a go at building a laser from scratch, using the diode driver seen here: http://www.laserpointerforums.com/forums/YaBB.pl?num=1185701612 I have an unwanted torch that will make an...

I got my two 50mW greenies today. I am very impressed with them, so are my kids. We can't wait until it's foggy here now  lol. I also rehoused my two 5mW reds too, but I can only attached one pic at a time, so here are the greenies.

I now have two new 532nm 50mW greenies. About bloody time too. The beams are well cool, but I am easially impressed   ::). I'll take a few pics later. However, one of the laser beams could be collimated better. I have taken a look at the 'pen style' housing but it seems to be spot welded...

Hi. This is a question for the guys with some electrical 'know how'. I am going to make a Spirograph, so my kids can use it to make pretty patterns on the walls. I know that it consists of two motors with mirrors on them, set at the correct angles. However I want to be able to control the...

Is there a way to work out the output of a laser beam using some sort of formula or does the beam have to be messured using one of those thermopile based meter thingys? For instance, if you made a laser yourself using a diode taken out of an old DVD RW or something similar, how could you...

What is the main difference between a class IIIa, IIIb and IIIc? I assume it's to do with the power output. Is there a chart or something that shows the difference? What class would my 670nm 5mW lasers come under? Thanks.

Here is a photo of my two 5mW lasers. They look a bit lame compared to some powerful lasers on here  :). One is on it's way out now and is much dimmer than the other. The photo was taken with a half second exposure and a bit of smoke helped too. In a few weeks I will be getting two 50mW...

I have seen some lasers on various sites that have laser diodes rated at 1W or even 5W. However the resulting CW output is much lower, like 300mW or something similar. I don't know about laser diodes but if one is rated at say 1W does that mean it can produce a beam rated at 1W? If so, why are...

I'm a noobie at all this so forgive me if this is a really stupid question. As most people know, if you have a light in a dark room and you turn it on it will light the room up ::). If you had two lights in the room and turned the second one on, the room would be twice as bright 8-). If you...

Like the title says, what do you use your's for? Do you just point it at shiny things and try to impress your mates or do you use your laser for more useful stuff?

I found this site: w w w.megalaseruk.com/laser01.htm I thought the 300mW laser (at bottom of page) was rather cheap. Has anyone else bought from this site before?
