Yeah, same Meter leads and things will add noise in unexpected ways. Wire runs definitely add both resistance and inductance and affect the measurement. Maybe you already know about it or haven't run into it yet, but isolation can be another big problem. If the power supply isn't truly ground...

I'm sorry about any annoyance this may cause, but I do plan on selling these. Would you ask DTR for the names of his suppliers? Would you ask Angelos what all the chips are he uses on all his boards? This is nothing personal. I don't know who any of you really are. I don't make it a habit to...

What is the ripple like @300mA - 500mA? The PLP520-B1 likes to run 7V @ 500mA, but a 40mA ripple might kill it.

Here are some pictures from the first test. I haven't set up a sales thread or anything just yet. If you want to talk about it or see more pictures or anything, just send me a PM. :beer:

I haven't decided what I am going to do with my C-mount. I ran into so many problems with my build. Now that there is a 638nm C-mount with FAC and everything, I'm not sure why everyone seems to want the old 660nm diodes all of a sudden.

They reflect light of the desired polarization back into the resonator to "seed" the oscillator. Again not sure here, but I think it has to be the 1064nm Nd emission. I'm not sure this can be done after the OC. It might need to be part of the resonator itself. A good high power lab module...

Yea, it looks like he is using 0603 in some places. Those can be a pain, though not quite as bad as mixed 0603 and thru-hole with tinned traces. :D

I'm fairly sure the polarization is random unless the resonator has been designed with a particular polarization state.

I like how you draw little arrows on there. Can they boost to 7V, and if so, how much current?

I think there has been a horrible accident or a tool crash or something. :(

ultimatekaiser is correct. Unfortunately, there is no mirror that can do this. I think a beam cube can be used to combine 2 DPSS lasers, but I am not 100% sure on that. It depends on polarization, so the lasers would probably have to be rotated in odd positions. It would also be very...

No. The modules will handle all that. Just wire them in parallel groups and you will be fine. And make sure the lasers are firmly mounted and terminate on the LDRs. We really don't need laser beams going everywhere and possibly into an audience.

Sorry, I thought this was another one of those fapril ool 'jokes'. I was not aware the SXD could go up to 7 amps. Everyone else was saying 5 MAX. And thanks for the picture, too. It helps clear up a little idea I was having amongst myselves. :D

It is also illegal in any Sensitive Flight Zone at any elevation between X and Y. You need to consult the maps published showing the FAA laser related flight zones. April fool. There are no maps, there never have been, and now they have even pulled the document pertaining to these laws. This...

Oh oh, isn't that the one that is both continuous positive and continuous ground at the same time? ;)

A beam expander does not make a rectangular beam "round".

Send him an e-Mail. It needs to be one of his special AMC drivers.

There is most likely a photodiode LPM out there or several that will do this.

There are some 808nm 500mW diodes on eBay selling specifically for green lasers. Just make sure you have the right safety glasses.
