I know there are many dimming lighting controllers for LED lights but can you dim a laser light?

If it can't be done electrically or electronically I'm pretty certain that putting photographic filter in front of it would do the trick. Of course if the laser is really powerful then it may burn out the filter

Yeah i've searched high and low for any information on it and can't find one thing. So i'm guessing only LED and PAR can kind of lights can be dimmed.

Lasers can be varied in power output, but it's done within the laser rather than using a separate dimmer. What unit do you have, and what are you trying to achieve?

I don't have one yet but I absolutely want the Laserworld EL-900RGB it's brilliant. I wanna use it in a pub venue which is the new venue i'll be doing dance music parties at. The problem is it's far too powerful.

Well despite the unit being dmx controlled it doesn't have a dimmer channel, so no way of "dimming" it on board. What makes you think it would be too bright? It's not a particularly high power unit, *disclaimer* that said it is a laser source so great care and attention needs to be taken with it or you can cause permanent ocular damage.

With lasers: in doubt do not use.. a pub will be rather low so you will be beaming into peoples eyes at a short distance. I looked at the movie of the effect and this is a fun machine but with half a watt can be dangerous if used in close proximity.

Possibly by turning down the diode drive current, but not guaranteed to work. Depends on the driver circuit.

If you think the laser is too powerful for the venue then you absolutely shouldnt be using it there. Part of the "official paperwork" is a risk assessment, which you have admitted to failing already.

What are you about pal? I've not said i'm absolutely going to use it and screw the risks have I? So what gave you the idea that I said that? Read it properly I said I absolutely want the laser I didn't say i'm absolutely using it in the pub. If I didn't care about the risks I wouldn't of asked if it could be dimmed would I.

It's more than that it's 900mw not 500mw, i'll be buying the laser regardless because I might be able to use it somewhere else and i'll test it out when I get it but if it is indeed too powerful it won't be used in the pub. Here is the video to show you how powerful it is, and this is in a medium sized warehouse/lighting demo room. |

900mW in total, I haven't looked at the specs, but you'll probably find its something like, 500mW red, 100mW green and 300mW blue.
