According to the recent studies performed by boffins it was stated that lasers are presently being considered as "non-light" emitters as opposed to piercing bolts of laser-light.

The dark pulse lasers are composed of minuscule quantum dot crystals, where these minute crystals convert into light once an electrical current strikes them. Each crystal dot behaves as an individual atom and then emits dark light at the same frequency. And these beams of light are shorter but more stable.

The boffins claim that these laser rely on qdots' unusual energy dynamics, which have the effect of stabilizing dark pulses who are known to recover energy from within rapidly (in about 1 picosecond) but more slowly (in about 200 picoseconds) from energy inputs originating outside the qdots in the laser cavity .

This procedure leads develop a progression of overall energy gains gradually giving way to overall energy losses.

Meanwhile substantial amount of work is being done in this area as the US National Institute of Standards and Technology reports.
