The laser emission is made up of spikes of high intensity emissions. This phenomenon is called spiking of the laser. After the depletion of E2 state, the laser action ceases for a few microseconds. ... So the output laser will be in the form of pulse in ruby laser or in other words, it will not be continuous.

Why ruby laser is called pulsed laser?

The ruby laser is used as a pulsed laser, producing red light at 6943Å. After receiving a pumping flash from the flash tube, the laser light emerges for as long as the excited atoms persist in the ruby rod, which is typically about a millisecond. ... It produces flash of few milliseconds.

Is ruby laser pulsed or continuous?

The laser did not emit a continuous wave, but rather a continuous train of pulses, giving scientists the opportunity to study the spiked output of ruby.
