One of the impulses that are translated into motion and causing physical changes of rhythmic waves. Femtosecond lasers are the fastest in the world and are capable of producing energy pulses that last a millionth of a billionth of a second and can be focused into beams less than one hundredth the diameter of a human hair.

1. A small dense star that emits brief intense bursts of visible radiation, radio waves, and X-rays, and is generally believed to be a rapidly rotating neutron star.
2. A blend of pulse and quasar.

• Pulse: A brief temporary change in a normally constant quantity, e.g. in a voltage, or a series of intermittent disturbances that are regular in form and frequency of occurrence.
• Quasar: A compact object in space, usually with a large red shift indicating extreme remoteness, that emits huge amounts of energy, sometimes equal to the energy output of an entire galaxy.

A Wave Inverter which is a type of power inverter that produce a high quality (nearly sinusoidal) voltage, at minimum current harmonics.
