Baker Leader... get your fighters clear of the pulse wave.

See, when stimulated correctly it sends out waves and waves of rhythmic pulses.

Note 1 Pulsed "lasers" include those that run in a continuous wave (CW) mode with pulses superimposed.

Note 1 Pulsed “lasers” include those that run in a continuous wave (CW) mode with pulses superimposed.

Item 28.14(g) above does not include the higher power (typically 1 to 5 kW) industrial CO2 lasers used in applications such as cutting and welding, as these latter lasers are either continuous wave or are pulsed with a pulse width greater than 200 ns.
