Self..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 کاملInjection locking of an actively mode-locked semiconductor laser.
We report what is to our knowledge the first observation of synchronous coherent injection locking of an actively mode-locked extended cavity semiconductor laser to an external light pulse train. In the temporal domain, we observed experimentally and verified theoretically a significant narrowing of the output pulse of the mode-locked laser. In the spectral domain, we demonstrated experimentall...
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.
متن کاملGigahertz self-referenceable frequency comb from a semiconductor disk laser.
We present a 1.75-GHz self-referenceable frequency comb from a vertical external-cavity surface-emitting laser (VECSEL) passively modelocked with a semiconductor saturable absorber mirror (SESAM). The VECSEL delivers 231-fs pulses with an average power of 100 mW and is optimized for stable and reliable operation. The optical spectrum was centered around 1038 nm and nearly transform-limited with...
متن کاملSelf-starting Kerr-lens mode locking of a Ti:sapphire laser.
It is shown that Kerr-lens mode locking of a Ti:sapphire laser, with no intracavity elements except the laser rod and the dispersion-compensating prisms, can be made to be completely self-starting. We achieve this result by carefully designing the resonator to maximize the nonlinear mode variations and dynamic loss modulation.
