Laser power scaling
open-in-new
<p>Power scaling of a <a href="/facts/Laser/jk6PTvvT">laser</a> is increasing its output power without changing the geometry, shape, or principle of operation. Power scalability is considered an important advantage in a laser design. This means it can increase power without changing outside features. </p><p>Usually, power scaling requires a more powerful <a href="/facts/Laser_pumping/nDlFU5QA">pump</a> source, stronger cooling, and an increase in size. It may also require reduction of the background loss in the <a href="/facts/Optical_resonator/BITPG3ga">laser resonator</a> and, in particular, in the <a href="/facts/Gain_medium/Gmcharyh">gain medium</a>. </p>
