We have one of the world's most powerful lasers in town. I have no idea how much load this puts on the electrical system when the capacitors are being charged. Some time in the past I have commented on this laser. Its peak power output is huge. I don't remember its value, but it gets compared to the average power consumption in the world.

Early this morning, about 4 AM, I looked at frequency using frequency mode for a short time. My 10 second average readings varied from 59.9 to 60.3 Hz. A little wider variation than earlier. Most readings were 60 Hz. Just now frequency is more stable. I am reading mostly 60.0 Hz with a few excursions to 59.9 Hz.

Why in the middle of the night did I see a slightly wide variation? I did not look at voltage during these measurements.

Yeah, but the duration of the pulse is probably measured in femtoseconds.

Since the overall load is lighter in the wee hours of the morning, I wonder if it's early-bird industrial loads coming on or off line? Single loads would be a larger percentage of the overall load at that time (maybe?).

P. S.
Yep, went to the ZEUS website, and the pulse duration is 20 femtoseconds.

What do you use that laser for, if you can tell me without having to kill me afterwards. :D

The University of Michigan has been well known for its research in optics for a long time. I remember reviewing some of the accomplishments and findings of Leith and Upatnieks of UofM in holography during an optics course in college.
