Hi everybody, because the 400mw green laser is so often sold out I'm thinking about buying a 350mw green laser module. It is IR filtered, so is there 100% green light? Has anybody experience with it and need it an extra heatsink (i think so) ?
Would it be visible as the 400mw green laser which is not IR fitered?
Does somebody know when the 400mw green laser will be back?

Sorry if my english is not perfect ;)

Thank you all for help :)

The 400mw laser will most likely return, as it has before and if something sells out, why not replenish stock?

Heatsink: Probably, 350mw of green probably has a really high pump diode.

On to your question about IR, you're asking if a 350mw green laser will be visible as a 400mw with some IR? Well there's two ways to look at this, assuming the 350mw laser is completely IR free.

1. The 350mw laser is 350mw of 532 wavelength. The 400mw laser is 400mw of 532 and some additional IR, putting the total laser power above 400mw.

2. The 350mw laser is 350mw of 532 wavelength. The 400mw laser is 400mw total power, meaning that the IR is factored into the power, so you could have 330mw of green and 70mw of IR.

IR is hardly visible to the eye, the dot of a 1000mw laser will barely be visible to the human eye.

Er. According to o-like's site, they currently have both the 'normal' 400mw and the new 'crown upgrade' 400mw's in stock.
