So the makers of the weapons plan to use a UV laser to fire a 5-joule pulse lasting just 0.4 picoseconds - equating to a momentary power of more than 10 million megawatts.
Uhhhh, I use class IIIb Lasers and they are .05 to .5 watt and CAN harm your eyes..
a quote
"""Class IIIb lasers are intermediate power (c.w. 5-500 mW or pulsed 10 J/cm²) devices. Some examples of Class IIIb laser uses are spectrometry, stereolithography, and entertainment light shows. Direct viewing of the Class IIIb laser beam is hazardous to the eye and diffuse reflections of the beam can also be hazardous to the eye. Do not view the Class IIIb laser beam directly. Do not view a Class IIIb laser beam with telescopic devices; this amplifies the problem. Whenever occupying a laser controlled area, wear the proper eye protection. Refer to the University of Kentucky Laser Safety Manual for complete instructions on the safety requirements for Class IIIb laser use."""

10 Million MEGAWATTS????
0.4 picoseconds.
