Pulsed laser sources

摘要: Modelocked fiber laser resonators may be coupled with optical amplifiers. An isolator optionally separate the resonator from amplifier. A reflective element on one end of having a relatively low reflectivity employed to couple light Enhanced pulse-width control provided concatenated sections both polarization-maintaining and non-polarization-maintaining fibers. Apodized Bragg gratings integrated polarizers also included in cavity assist linearly polarizing output cavity. Very short pulses large bandwidth obtained by matching dispersion value grating inverse intra-cavity fiber. Frequency comb sources constructed such modelocked oscillators. Low an in-line interferometer that provides feedback controlling frequency components source.
