For pulsed lasers the controller should be locked to the repetition rate.
However, they are less well suited to the high peak powers of pulsed lasers.
The light has a very high intensity (typically from a pulsed laser).
A pulsed ruby laser is normally used for developing a high power.
To do that, engineers need a 1,000-watt pulsed laser as described here:
They used a pulsed optical laser, where each pulse consisted of exactly 532,361 oscillations.
For pulsed lasers and invisible wavelengths, other power limits apply.
And continue they did, employing pulsed lasers and cannon fire.
That in itself fell far short of the needed energy, even though the pulsed green laser is one of the world's most powerful.
Another scheme uses a pulsed laser as the excitation source.
