Optical cavity gain

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. WebGain chips are semiconductor optical elements used as the optical gain medium of external cavity laser diodes. Gain chips are used as a TLS (Tunable Light Source) that can change the oscillation wavelength using a wavelength selection filter such as a diffraction grating.
