Mode locking of a wavelength-swept laser.
Self-starting, stable mode-locked pulses can be generated from a wavelength-swept laser through the interplay between an intracavity scanning filter and self-phase modulation. From an Er3+-doped fiber laser employing a scanning Fabry-Perot filter, 100 ps optical pulses are obtained at a 12-MHz repetition rate with center wavelengths that are swept over 27 nm around 1.55 microm in 1 ms.
متن کاملMode-locking of a CW laser
Short pulses are useful in a number of applications in optics, e.g., time resolved spectroscopy, sampling of fast electronics, and communications. This has led to a number of mode-locking techniques to obtain such pulses, for example acousto-optic, injection, synchronous-pump, collidingpulse mode-locking, and Kerr-lens mode-locking. Using the latter two techniques, pulses of less than 100 fs du...
متن کاملSelf..mode",locking of a semiconductor laser
Active-mode locking of semiconductor lasers has pro duced optical pulses as short as 0.58 ps.! This result was achieved using the positive portion of a 16 GHz sinusoid as an electrical drive signal. For many applications, such as electro-optic sampling, it is more useful to have the mode locked optical pulses at a much lower repetition rate. This requires an electrical drive source that produ...
متن کاملMode-locking of a terahertz laser by direct phase synchronization.
A novel scheme to achieve mode-locking of a multimode laser is demonstrated. Traditional methods to produce ultrashort laser pulses are based on modulating the cavity gain or losses at the cavity roundtrip frequency, favoring the pulsed emission. Here, we rather directly act on the phases of the modes, resulting in constructive interference for the appropriated phase relationship. This was perf...
متن کاملSelf-starting additive-pulse mode locking of a Nd:YAG laser.
We report additive-pulse mode locking of lamp-pumped Nd:YAG lasers at both 1.06 and 1.32 microm. Under completely self-starting conditions, stable cw mode-locked trains of 6-psec pulses have been achieved at an average output power of 2.4 W.
