For this reason the spectral properties of the OC are important to consider when a laser cavity is being assembled.

Preventing the feedback of a laser cavity by using a polarizing prism.

(the difference determines the optical energy, which is output from the laser cavity at each round-trip).

It is typically used to prevent unwanted feedback into an optical oscillator, such as a laser cavity.

The laser cavity probed 100-200 of these discharges in series providing the laser gain.

In the laser cavity short bursts of light will then be focused differently to continuous waves (cw).

It can also be used to compensate for dispersion of ultrashort pulses outside laser cavities.

This type of beam divergence is observed from optimized laser cavities.

The grey dots represent molecules in the laser cavity that act as resonators.

A major difficulty with these systems is preserving the high-precision mirrors and windows of the laser resonating cavity.
