= Laser light
<Laser light> is <radiation> produced by a <laser>, in which <stimulated emission> and feedback select and amplify optical modes. It can have high directional concentration, a narrow spectrum and strong coherence compared with ordinary thermal sources.
These are properties to quantify, rather than guarantees of perfect monochromaticity or one universal intensity distribution. A pulsed laser has finite bandwidth, and a multimode laser can have several <frequencies>. The emission's <temporal coherence>, spatial mode and <polarization> determine which <interference> or focusing <experiments> it supports.
