Don't forget that is the estimated power *density* in W/cm^2 over a beam waist cross-section of only 30 microns diameter. From the description, it appears to be a diode pumped Nd:YAG laser that is frequency doubled (as are most green lasers today). The 5ns pulse implies Q switching. It is a pretty powerful class IV laser. At 200mJ/pulse and 10pulses/second, that's 2000mJ/s or 2W average power of green light that has been focused. If you look around on the web for what a 2W focused laser can do (and green focuses to a smaller spot than IR), you will see it igniting common materials, and capable of metal marking via evaporation. This is not a "small" laser like a laser pointer - probably about 500x more. But it is also not a SHIVA for hot ICF.
