And yes, I will use pulsed laser of course. It can be modulated in any way since electronics is prepared for this.
A continuous wave (CW) laser electronically modulated to irradiate the target impulsively will not work as a pulsed laser.
The energy of each individual pulse will be several orders of magnitude lower.
In the excerpt above Holmlid used his laser at 0.4 J/pulse, with each pulse having a 7 nanosecond duration.
Since [W=J/s], each pulse would have a peak power of about 57 megawatts.
These lasers are actually not that much specialized or expensive, but they're on a different category than ordinary laser pointers.
