The coupling parameter of a laser resonator determines, what part of the energy of the laser field in the cavity goes out at each round-trip.

It may also require reduction of the background loss in the laser resonator and, in particular, in the gain medium.

When used as intracavity beam expanders, in laser resonators, these telescopes provide two-dimensional beam expansion in the 20-50 range.

In tunable laser resonators intracavity beam expansion usually illuminates the whole width of a diffraction grating.

Injection locking and pulling effects are observed in numerous types of physical systems, however the terms are most often associated with electronic oscillators or laser resonators.

As a new type of laser resonator, he proposed, in 1958, an "open type" cavity design, which is widely used today.

Etalons are often placed inside the laser resonator when constructing single-mode lasers.

He joined with G. Boyd, to introduce the concept of Hermite-Gaussian modes into resonator study, influencing all subsequent research conducted on laser resonators.

It has been shown that unstable laser resonators (not used in most lasers) produce fractal shaped beams.

Unstable laser resonators on the other hand, have been shown to produce fractal shaped beams.
