Thx for reply and I have another question... To get above 1W, I need 4x 250mW diodes, which I could cheaply extract from DVDs. As far as I remember from primiary school, if I put parallel rays trough a magnifying glass, they are focused in a point, depending on the focal length of the glass...

Lotus_Darkrose, thx for reply Yes, I understand that this guy was very excited, but he didn't exactly know what is he excited about:). But as to facts, this diode of his was 250mW with efficiency of 0,97 W/A and he delivered 650mA. I'm not sure what is the linear range of this efficiency but...

High, I've searched the forum but I haven't found any info. Did anyone try to use 500mW diode cooled to bellow -20*C, and double or triple its power? I want to cut a 3mm aero-depron and my guess is that I need 1W+ power to cut it at reasonable speed. Since the cost of diode increase...
