US Projector Regs

And I suppose that if your electronic shutters contacts weld shut then you have a fail safe?

Sure, the shutter on my big (400w) yag has a position switch on the shutter mirror itself, it the shutter is activated and it is not in position or deactivated and not in that position it shuts everything down.

I dont see why you wouldnt want to have a mechanical shutter in your system.

daction, what kind of bird do you have?

I asked one of the most experienced US laser safety engineers what he thought of the "No Shutter with DPSS"concept. The answer was "Don't do it". I'll explain his reasoning when I get back from SELEM.

Hey,

Henry is a female yellow Indian Ringneck.

Any chance of a pic of the shutter on your laser?

I was talking to a mate of mine about this yesterday. He was like you can power down your coils , however if you haven't got the shutter you can't be sure its off.
As for the size thing. It shouldn't matter if your laser is big or small safety features should be standard. Its called industry standard.
A simple electric hot water system has at least 3 fail safes in it. The valve chain to a forced induction burner has heaps of interlocking safety features.
