great link, really simple to follow compared to text. saved the entire process, will be working on something shortly.

ok, so if you're combining the lasers you need to first determine how you want to do this. You can work with the crystals if you know what you are doing, but you will need to house the diode in one casing. That is going to be pretty tricky.

If you can combine the beams, or cross them you can get ...

pricing is nice, but what is the expeted lifetime? type of diodes? such a low cost can be great unless the devices are really poor machines.

You can control any laser display system on your PC that is compatible as such. I believe the model you are referring to uses DMX controllers which attach to the laser and are controlled through software on your computer. This is the only way to input custom text, designs, and animations.

that ...

Yes, if you know how to properly collimate a laser beam. You will need to manipulate the diode so that the beam being produced is more dense. Be careful though, it can be hard dealing with "in case" diodes, and you are risking damaging or destroying the laser crystal all together. But yes, if you ...

if the beam is not shining straight from the pointer you have a problem with the collimation and the pointer is damaged. I'd look for a return, modding it yourself to fix the problem with diode can be complex and you may risk losing your laser all together. If the beam isn't straight, something is ...

Hi Brian,
try www.jmlaser.com Easylase USB (12 Bit XY, 4 x 8 Bit Color channels, ~ 350€)
or www.riyalasers.com RIYA USB (12 Bit XY, 6 x 8 Bit color channels, ~ 550€ ).
Both have a Delphi SDK. Most other DAC Boards are sold only with a software package.

Greetings,

those are a bit over ...

If you are looking to see the "dot" after 120-200m during the day time you are going to need something relatively powerful. As the beam goes away from the laser it disperses, when there is daylight this dispersing is faster and the beam can be seen less.

At night you may not have the problem, but ...

I've tested hundreds of lasers. What beam frequency (color) were you thinking of?

from .01mW-8000mW pointers and industrial dpss lasers. let me know what you are looking to accomplish
