Abstract
Coating-less nonplanar ring oscillator lasers are disclosed. Such lasers may eliminate the need for thin-film optical coatings from a laser cavity, solving the problem of optical damage to the coatings, and thus, providing a longer useful lifetime for the laser for space or terrestrial applications. Such lasers may be compact, ultra-stable, and highly reliable, enabling a low phase noise, single frequency laser in a compact package. Such lasers may be used in CW and/or in pulse mode.
