WebThe optical cavity has a stronger effect on the gain of a FEL than in most conventional lasers and the gain can also affect the optical mode. The gain is maximized for an optimal overlap between the electron beam and the optical mode. WebA laser generally requires a laser resonator (or laser cavity), in which the laser radiation can circulate and pass a gain medium which compensates the optical power losses. Exceptions are a few cases (e.g. some free … WebApr 12, 2024 · The use of a quasi-optical cavity with a traveling wave and with a Bragg-type photonic structure providing coupling between the gyrotron wave pulse and the operating wave of the cavity makes it possible to obtain the electric field strength required for breakdown at lower generator power values compared to the case of direct focusing. orban\u0027s oral histology and embryology pdf
