[time-nuts] science projects

[Bill Fuqua]

     My experiments with CW laser diodes is that they don't take well to 
being switched on and off with out a soft start.
They will only last a certain number of on off cycles before output begins 
to drop and they quit working. Perhaps something
has changed in the last few years.
     I need to do some experiments with these myself. Maybe they have 
improved.
Alignment of the mirror is  not easy either.
