Compact fiber-based short pulse laser sources -

摘要

Examples of robust even start ends passively mode-locked fiber oscillators are described. In certain implementations as the oscillators are configured fabry - perot - resonators, which is formed by an optical grinding on the one resonator end mirror and a voluminous mirror or a saturable absorber at the other end comprise. The grinding mirror can be further comprising an adaptable phase delay path be configured, in order to optimize mode locking. All located in the resonator fiber (n) can be polarization. Dispersion-compensating components such as, for example, dispersion-compensating fibers, voluminous diffraction gratings or fiber bragg grating - - can be enclosed. The oscillators can comprise a bandpass filter - filter, in order to obtain high pulse energies, when they operate in the similariton - regime. The oscillator - output can be amplified and are to be used whenever short pulses with a high power are required. For example, the oscillators as the frequency comb - sources or super continuum - sources are configured. In connection with a modulation of the repetition rate, the applications dual sampling - delaying paths and trace gas - detection.
