change laser polarization
35mW at 405nm is plenty in any case. You'll get sensitivities around 2mJ/cm2 DCG (2g gelatin / 0.085g Amdi / 16.5ml H20).

change laser polarization

Issues with forum server
Thank you for reporting. I wasn't able to pinpoint the cause for the mismatch, both domain names should point to the same ip. If you experience this issue again, it would be much appreciated if you could let me know.
Thanks,
Ahmet
