LASER | Remote Sensing Branch - NASA
A laser emits in only a very small portion of the spectrum. We speak of red lasers or green lasers or blue lasers but not white light lasers.
What Are Lasers And How Do They Actually Work? - ScienceAlert
Lasers are devices that concentrate beams of light by forcing their waveforms and frequencies to align.
