Question

Question reguarding laser power... Answered, Thanks!

I am kind of confused about mw ratings for blue lasers. I see talk of blue lasers upwards of 400mw so why is it that a 30mw blue laser from Optitronics costs $1,400? What am I missing? Thanks

There is a significant difference between "bluray" (405nm) and "blue" (473nm).

The "bluray" (405nm) is the less expensive and more powerful in hand held units AND the color is actually violet (405nm), NOT blue (473nm).

Peace,

P.S. Sucky title

This section is for Blu ray or violet lasers, 405nm. Blue is 473nm and is a really rich blue. Some of our members using 8X diodes are getting around 400mW of violet light and is relatiely easy as it can be produced straight from a diode at a cost much less than a blue DPSS laser. The blue you are referring to is produced with a pump diode and special crystals to produce 473nm. Because of this, blue is much more expensive as material costs are higher as well as an increased complexity of the build. However thats not to say you cant get 400mW's of blue(473nm). However, that would require a lab style laser with power supply, and cost many thousands of dollars.

EDIT: Wow Dave, your quick. The thread was clear when i read it and when i posted, there you were!

Great, thanks for the replies! That clears a lot up. So what would a 30mw 473nm laser compare to against a 405nm... Basically can a 30mw 473 burn or is it really just for the "Blue" look?

30mw true blue is still 30mw, so it's won't burn. If you want burning you should go with blu-ray.
