No. It wasn't required until '92 just as I was laid off.
Anyhow, wearing goggles is stupid for that kind of work. You're centering the beam past two stationary mirrors up to a oscillating mirror.
That would be pretty tough to do if you're wearing goggles and can't see the beam.
I always wondered about that. What do people who need to see the laser beam do when they are required to wear protective goggles that make the beam invisible? I guess they have to rely on phosphor cards & stuff.
