quarter wave plate = circular polarization or elliptical polarization, which is why it works. Your thinking half wave plate.

So are you going to get some of this stuff Steve? Or what would you recommend me order and from where?

I'll try to call them today for a test piece.

How can you tell a diode is killed by back reflection instead of ESD/lifetime/overcurrent etc.

Since I'm running with PBS I allready killed 3 diodes without a reason. I thought this was becouse of ESD. Before I was running with 1 the diode last very long.

mccarrot, are you using a sound card dac?

**mccarrot** · 03-18-2009, 10:34

No, I'm using QM.nets

When I still used the easylase I also didn't had that many broken diodes, but this can be coincidense.

Now I just added 6.8V directional transorbs on the ilda port and 15V unidirectonal transorbs paralell over the laserdiodes. Bill told me transorbs doesn't protect the diodes all the way, but hey I think its better than nothing
