Viasho 4W 532nm Laser System Review!

See the power supply which is OK for FDA

Superb review ben , pictures are always good

Man that guy has some sloppy wiring wondering who would even post a picture like that

Great review tho.... just wondering probably don't want to know but whats the $ amount a a beauty like that.

so when can we expect to see in in the for sale forum as a slightly used 6 watt 532 viasho?

Hey,Michael

Just using your pic.

Thanks

Just wondering, how much pump power is used in IR for this 4W to come out ?

Very nice review Ben

Now I know what that little space on my workbench is missing

Based on the current being drawn, I'd guess it's a 10W pump source, but 4W+ of green out for 10W in is incredibly efficient. Not too surprising these days, though, with crystal quality being constantly improved.

Well, threshold for green is around 1.26A according to the power supply, assuming there is lasing before that, let's assume a 1.1A threshold with a 1W/A slope efficiency. That means that it will make around 9W at 10A (assuming the current is correct). That means there is a 44.5% efficency pump to green. This is very high, I am guessing the current is either scaled or not correct. I will check for IR as I have not done that yet. Perhaps there are more then 1 diode and they are run in series.

Very nice review Ben! I also noticed the class IIIb sticker, that should be changed but is no big deal with the overall quality of the rest of the unit. Looks like a great module!
