I managed to grab a few SLD3134VF laser diodes which are supposedly 20mW 405nm diode that run at 35-50mA, however i tested a few diodes from the batch i got and i can run them at 100mA+ allowing these diodes to start burning if focused and they get very bright for 405, anyone had similar experiences when using these Sony diodes?

You might got not SLD3134VF but a more powerful version. Do you have a Sony datasheet for this diode? My googling for SLD3134VF gave only 21 result. imho, a fake :)

Can you measure the threshold current?

Yes, most likely fake as the datasheet i was supplied was kinda sketchy, ill send em some more messages and see just how far the diodes can go.
